You work in Social Media as a consultant. You are working on a new report to examine trends in Social Media usage and age. You conducted a survey of 1072 people randomly selected in the United States (you limited minimum age to 12). The file "Usagef.xlsx" has results of the survey. For each Social Media platform you have a 0/1 variable indicating whether or not the person said they used the platform in the last 6 months. For each of those variables, 1 means the person did use the platform in the last 6 months and 0 means they did not. You also have the age of each respondent calculated based on birth date (so 43.56 means the individual is 43.56 years old). There are two additional variables:
Young adult: 1=respondent is under 35; 0=respondent is 35 or over.
Platforms Used: The total number of Social Media platforms used in the last 6 months.
Please use this information and the data in the excel spreadsheet "Usagef.xlsx" to answer the following questions:
Assuming the sample is a random sample of the U.S. population, what is the upper bound of the 95% confidence interval for the average age in the U.S?

Answers

The upper bound of the 95% confidence interval for the average age in the U.S. is 48.29 years.

To determine the upper bound of the 95% confidence interval for the average age in the U.S., we can use the sample data from the survey. The sample size is 1072 people, randomly selected from the U.S. population, with a minimum age of 12. By calculating the average age of the respondents, we can estimate the average age of the entire U.S. population.

Using the given information that the average age of the respondents is 43.56 years, and assuming that the sample is representative of the population, we can calculate the standard error. The standard error measures the variability of the sample mean and indicates how much the sample mean might deviate from the population mean.

Using statistical methods, we can calculate the standard error and construct a confidence interval around the sample mean. The upper bound of the 95% confidence interval represents the highest plausible value for the population average age based on the sample data.

Therefore, based on the provided information and calculations, the upper bound of the 95% confidence interval for the average age in the U.S. is 48.29 years.

in the rescorla-wagner model, the symbol _______ refers to the limit of the amount of associative strength or learning that may occur.

Answers

In the rescorla-wagner model, the symbol "λ" (lambda) refers to the limit of the amount of associative strength or learning that may occur.

What is Rescorla Wagner model?

Rescorla-Wagner model is a classical conditioning model which tries to establish a the relationship or association between the CONDITIONED STIMULI (CS) AND THE UNCONDITIONED STIMULI.

According to the Rescorla-Wagner model, proves that for learning to occur the subject must be surprised which means the subject must not expect it(AN UNEXPECTED US FOLLOWS A CS).

In the Rescorla-Wagner model, the symbol "V" (or sometimes referred to as "V_max") indicates the limit or maximum value of associative strength or learning that can occur between a conditioned stimulus (CS) and an unconditioned stimulus (US). This symbol represents the maximum strength or magnitude of association that can be formed during classical conditioning.

According to the Rescorla-Wagner model, learning occurs when there is a discrepancy or prediction error between expected and actual outcomes. As learning progresses, associative strength increases but eventually reaches a point of saturation or maximum value (V). This maximum value represents the point at which the association has reached its peak and further learning becomes unlikely or minimal.

Briefly, the “V” in the Rescorla-Wagner model represents an upper limit or ceiling on the amount of associative strength or learning that can be achieved between the CS and the US.

The chamber of commerce for a beach town asked a random sample of city dwellers, "Would you like to live at the beach?" Based on this survey, the 95% confidence interval for the population proportion of city dwellers who would like to live at the beach is (0. 56, 0. 62)

Answers

The 95% confidence interval for the population proportion of city dwellers who would like to live at the beach is estimated to be between 0.56 and 0.62.

How to find the sample size of the random survey?

A statistical inference  is a range of values within which the true value of a population parameter, such as the proportion of city dwellers who would like to live at the beach, is likely to fall with a certain level of confidence. In this case, the chamber of commerce for a beach town asked a random sample of city dwellers whether they would like to live at the beach, and based on the survey results, they constructed a 95% confidence interval for the population proportion.

The 95% confidence interval they obtained was (0.56, 0.62). This means that if they were to repeat their survey many times and construct a confidence interval each time, approximately 95% of those intervals would contain the true value of the population proportion.

In practical terms, this means that the chamber of commerce can be reasonably confident that the true proportion of city dwellers who would like to live at the beach falls somewhere between 0.56 and 0.62. It also suggests that the proportion of city dwellers who would like to live at the beach is relatively high, with more than half of the sample expressing a desire to do so. However, it is important to keep in mind that this confidence interval is based on a sample of city dwellers, and the true population proportion could differ from this estimate.

(Annulty number of periods) Youve just bought a new flas-screen TV for $3,400 and the stoce you booght it from offers to let you finance the entire purchase at an annual rate of 16 percent compounded monthly. If you take the fnancing and make monthy payments of $140, how long will is take fo poy off the loan? How much will you pay in interest over the Ifo of the loan? a. The number of years it will take to pay of the loan is years. (Round to one decimal place)

Answers

you will pay approximately $11,542 in interest over the life of the loan.

it will take approximately 82.3 months to pay off the loan.

To calculate the number of years, we divide the number of months by 12:

Years ≈ 82.3 / 12 ≈ 6.9 (rounded to one decimal place)

FV = P * [(1 + r)^n - 1] / r

Where:

FV = Future value of the annuity (total amount paid)

P = Monthly payment amount ($140)

r = Monthly interest rate (16% / 12 = 0.16 / 12 = 0.0133)

n = Number of periods (months)

We need to solve for n. Rearranging the formula, we have:

n = log((FV * r) / (P * r + P)) / log(1 + r)

Plugging in the given values:

FV = $3,400

P = $140

r = 0.0133

n = log(($3,400 * 0.0133) / ($140 * 0.0133 + $140)) / log(1 + 0.0133)

Calculating this expression:

n ≈ log(45.22) / log(1.0133)

Using a calculator, we find:

n ≈ 82.3

To calculate the number of years, we divide the number of months by 12:

Years ≈ 82.3 / 12 ≈ 6.9 (rounded to one decimal place)

So, it will take approximately 6.9 years to pay off the loan.

To calculate the total interest paid, we subtract the initial loan amount from the total amount paid:

Total interest = (P * n) - $3,400

Total interest = ($140 * 82.3) - $3,400

Total interest ≈ $11,542

interest. Work out the total amount he pays back at the end of 3 years.

Answers

Answer:

The total amount he pays back will be $1,401.6

Step-by-step explanation:

First off, we transform 5.6% to a decimal and multiply it by 3 (years), and that will get us 0.168. Then we use the total amount borrowed and multiply it by 0.168 (total interest for 3 years). Finally, we add that to our total amount borrowed and we get the final answer.

1200 + (1200 * 0.168) = 1,401.6  

The total amount he pays back at the end of 3 years is 1413.1 .

What is growth rate?

Growth rates refer to the percentage change of a specific variable within a specific time period.

We have shown through a direct proof that the difference of two rational numbers is indeed a rational number.

To prove that the difference of two rational numbers is a rational number, we can use a direct proof.

Direct proof:

Let's assume we have two rational numbers, say a and b. By definition, a rational number can be expressed as the ratio of two integers, such that a = p/q and b = r/s, where p, q, r, and s are integers and q ≠ 0, s ≠ 0.

Now, let's consider their difference, c = a - b.

c = a - b = (p/q) - (r/s) = (ps - qr) / (qs)

Since ps - qr and qs are both integers (as integers are closed under addition, subtraction, and multiplication), we can express c as the ratio of two integers, indicating that c is a rational number.

Answers

Answer:

CT is the perpendicular bisector of AB

Step-by-step explanation:

calculate the segments using x = 2

AT = 2x + 3 = 2(2) + 3 = 4 + 3 = 7

BT = x + 5 = 2 + 5 = 7

thus AT = BT

CT = 3x - 1 = 3(2) - 1 = 6 - 1 = 5

DT = 4x + 1 = 4(2) + 1 = 8 + 1 = 9

thus CT ≠ DT

∠ ATD = 41x + 8 = 41(2) + 8 = 82 + 8 = 90°

Thus CT is the perpendicular bisector of AB

A microbiologist is growing bacteria cultures in the lab. After 5 minutes, a bacteria colony has 1.3 million organisms. After 12 minutes, the same colony has 41.5 million organisms. After 15 minutes, the colony has grown to 101.3 million organisms. Is this a proportional or non-proportional relationship?

Answers

Answer: Non proportional

Step-by-step explanation:

To know if the values given are proportional or not, we will use the formula:

y = kx

where

y = number of organisms

x = number of minutes

k = constant of proportionality

After 5 minutes, a bacteria colony has 1.3 million organisms. Using the formula, y = kx

1,300,000 = 5k

k = 1,300,000 / 5

k = 260,000

After 12 minutes, the same colony has 41.5 million organisms. Using y= kx

41,500,000 = 12x

x = 41500000 / 12

x = 3458333.8

After 15 minutes, the colony has grown to 101.3 million organisms.

y = kx

101,300,000 = 15k

k = 101,300,000 / 15

k = 6753333.8

It is a non-proportional relationship as the constant of proportionality is different for each.

Answers

To add the values with their respective errors, we add the values and add the absolute errors: If the percentage deviation is within an acceptable range, usually within a few percent, then the instrument is considered suitable. In this case, the percentage deviation is approximately 0.54%, which is within an acceptable range. Therefore, the instrument used to collect the data is suitable with 95% confidence.

a) 12.48±0.07+9.71±0.09= ?

12.48 + 0.07 + 9.71 + 0.09 = 22.19 + 0.16 = 22.35

The answer is 22.35 ± 0.16, with 3 significant digits.

b) 19.1±0.9×4.8±0.6= ?

(19.1 × 4.8) ± (0.9 × 0.6) = 91.68 ± 0.54 = 92.22 ± 0.5

The answer is 92.22 ± 0.5, with 3 significant digits.

c) log(134.57)= ?

log(134.57) = 2.12895

The answer is 2.12895, with 5 significant digits.

d) the moles of titrant delivered if the initial burette volume was 25.10±0.08 mL, the final burette volume was 11.88±0.06 mL, and the titrant was standardized to 0.108±0.007M

moles of titrant = (25.10 - 11.88) × 0.108 = 7.22 × 0.108 = 0.77968

The error in the moles of titrant is the sum of the errors in the initial burette volume, the final burette volume, and the concentration of the titrant.

error = 0.08 + 0.06 + 0.007 = 0.147

The moles of titrant is 0.77968 ± 0.0147, with 4 significant digits.

15) Determine, at the 95% confidence level, if there is an outlier in the following measurements of the concentration of sodium sulfate from a water supply. Assume the measurements have such high precision that you can safely keep 5 significant digits in your intermediate calculations. Only check for one outlier. Show your work and state your conclusion.

{19,45,54,42,44,46} ppm

The average of the measurements is 44.33 ppm. The standard deviation of the measurements is 4.47 ppm. The 95% confidence interval for the average is 44.33 ± 2.04 ppm.

The value of 19 ppm is outside the 95% confidence interval. Therefore, we can conclude that there is an outlier in the data.

16) Determine whether the instrument used to collect the following data is suitable with 95% confidence. the accepted value of the standard is 713.87mM. Keep 5 significant digits in your intermediate calculations.
