a paper questionnaire uses a 1-7 likert scale to determine satisfaction with the store experience from a convenience sample outside of a supermarket. when entering the data into a file, a researcher types an 8 instead of the 5 that the respondent had circled on the questionnaire. such a mistake can be uncovered by performing what type of analysis?
"Double-entry" can be used to find the error of inputting an 8 instead of a 5 in research.
Define the Double-entry?Each financial transaction involves equal and opposite consequences in at least two independent accounts, according to the fundamental principle of double entry, which underpins modern bookkeeping and accounting.
Transactions are recorded using the double-entry approach as debits and credits. The total of all debits shall equal the total of all credits because a debit for one account cancels out a credit in another. The accounting process is standardized, the created financial statements are more accurate, and errors are easier to spot thanks to the double-entry system for bookkeeping.As the question states-
An outside convenience sample is used to create a paper questionnaire that employs a 1–7 likert scale to gauge customer happiness. The researcher enters an 8 in place of the 5 that its respondent originally circled on the questionnaire when the information is entered into a file.Thus, "Double-entry and frequency analysis" can be used to find the error of inputting an 8 instead of a 5.

Two square posters are hanging on a wall. The large poster has an area of 144 square units, and the small poster has an area of 100 square units. How much bigger is the perimeter of the large poster than the perimeter of the small poster?
Answer:
8
Step-by-step explanation:
If you do the math with the area to find out the perimeter, and you will find the largest one to be the poster with the area of 144 , and the smaller one to be the one with the area of 100
Answer:
Length= squre root of area
Length of big poster = squre root of 144
=12
Length of small poster=squre root of 100
=10
The perimeter = 4*length
Big poster perimeter=4*12=48
Small poster perimeter =4*10=40
The difference= 48 - 40 = 8

For each question below, determine True or False: If a simple random sample is chosen with replacement, each individual has
the same chance of selection on every draw.
The statement If a simple random sample is chosen with replacement, each individual has the same chance of selection on every draw is True.
If a simple random sample is chosen with replacement, it means that after each selection, the chosen individual is placed back into the population before the next selection is made. In this case, each individual in the population has the same chance of being selected for every draw.
The process of replacing the selected individual ensures that the selection probabilities remain constant throughout the sampling process. As a result, each individual has an equal probability of being chosen on each draw, making the statement true.

If a motorbike travels 2.4 km in 5 minute find, its average velocity. please write step by step from which I could understand..
Answer:
8m/s
Explanation:
Given,
Distance covered (s) = 2.4 = 2.4 * 1000 = 2400m
Time taken (t) = 5 = 5 * 60 = 300
Now,
v = s/t
or, v * t = s
or, v * 2400 = 300
or, v = 2400/300
or, v = 8m/s
If the scale factor between the sides is 5, what are the scale factors between the surface areas and volumes?
If the scale factor between the sides is 5, the scale factor between the surface areas will be 25, and the scale factor between the volumes will be 125.
When the scale factor between the sides of a shape is given, the scale factors between the surface areas and volumes can be determined by considering the relationship between the dimensions.
Let's denote the scale factor between the sides as "k."
For surface area:
The surface area of a shape is determined by the square of its linear dimensions. Therefore, the scale factor for the surface area will be k^2. In this case, if the scale factor between the sides is 5, the scale factor between the surface areas will be 5^2 = 25.
For volume:
The volume of a shape is determined by the cube of its linear dimensions. Hence, the scale factor for the volume will be k^3. Given that the scale factor between the sides is 5, the scale factor between the volumes will be 5^3 = 125.
Therefore, if the scale factor between the sides is 5, the scale factor between the surface areas will be 25, and the scale factor between the volumes will be 125.

what is the probability that a player wins $100 by matching exactly three of the first five and the sixth numbers or four of the first five numbers but not the sixth number?
The probability of winning $100 by matching exactly three of the first five and the sixth numbers is 0.0018. The probability of winning $100 by matching four of the first five numbers but not the sixth number is 0.0003.
To calculate the probability of winning $100 by matching exactly three of the first five and the sixth numbers, we first need to determine the total number of possible combinations for the first five numbers. Since each of the five numbers can be any number between 1 and 69, there are 69 choose 5 (written as 69C5) possible combinations, which is equal to 11,238,513. Out of these 11,238,513 possible combinations, we need to choose three numbers that will match the drawn numbers and two numbers that will not match. The probability of matching three numbers is calculated as 5C3/69C5, which is equal to 0.0018. The probability of not matching the remaining two numbers is 64C2/64C2, which is equal to 1.
Therefore, the probability of winning $100 by matching exactly three of the first five and the sixth numbers is 0.0018 x 1, which is equal to 0.0018. To calculate the probability of winning $100 by matching four of the first five numbers but not the sixth number, we need to determine the total number of possible combinations for four of the first five numbers. Since each of the four numbers can be any number between 1 and 69, there are 69 choose 4 (written as 69C4) possible combinations, which is equal to 4,782,487.
Out of these 4,782,487 possible combinations, we need to choose four numbers that will match with the drawn numbers and one number that will not match. The probability of matching four numbers is calculated as 5C4/69C4, which is equal to 0.0003. The probability of not matching the remaining number is 64/64, which is equal to 1. Therefore, the probability of winning $100 by matching four of the first five numbers but not the sixth number is 0.0003 x 1, which is equal to 0.0003.

a partial sum of an arithmetic sequence is given. find the sum. 3 9 15 639
The sum of an arithmetic sequence given a partial sum is 35532.
Firstly, we need to identify the common difference of the arithmetic sequence. This can be done by finding the difference between any two consecutive terms. In this case, subtracting 9 from 3 gives us a common difference of 6.
Next, we determine the number of terms in the sequence. To do this, subtract the first term from the given partial sum and divide the result by the common difference. In this case, subtracting 3 from 639 and dividing by 6 gives us 106 terms.
Finally, we can calculate the sum using the arithmetic series formula: Sn = (n/2)(2a + (n-1)d), where Sn represents the sum, n is the number of terms, a is the first term, and d is the common difference. Plugging in the values, we have Sn = (106/2)(2*3 + (106-1)*6). Simplifying this expression, we find that the sum of the arithmetic sequence is 35532.

Can u plz mark me branliest plz.
Answer:
p = 50
Step-by-step explanation:
\(\frac{1}{2} *p+75=100\\\)
Combine like terms into a single fraction:
\(\frac{1}{2} p+75=100\)
\(\frac{1p}{2} +75=100\)
Multiply by 1:
\(\frac{1p}{2}+75=100\)
\(\frac{p}{2} +75=100\)
Subtract 75 from both sides of the equation:
\(\frac{p}{2} +75=100\)
\(\frac{p}{2} +75-75=100-75\)
Simplify:
Subtract the numbers:
\(\frac{p}{2} +75-75=100-75\)
\(\frac{p}{2} =100-75\)
Subtract the numbers:
\(\frac{p}{2} =100-75\)
\(\frac{p}{2} =25\)
Multiply all terms by the same value to eliminate fraction denominators:
\(\frac{p}{2} =25\)
\(2*\frac{p}{2} =2*25\)
Simplify:
\(2*\frac{p}{2} =2*25\)
\(p=2*25\)
Multiply the numbers:
\(p=2*25\)
\(p=50\)
Solution:
\(p=50\)

batting averages. suppose that a baseball player's long-run batting average (number of hits per time at bat) is .300. assuming that each time at bat yields a hit with a consistent probability, independently of other times, what is the chance that the player's average over the next 100 times at bat will be a) .310 or better? b) .330 or better? c) .270 or worse?
By the the application of Bayesian inference, chance that the player's average over the next 100 times at bat will be : 0 . 330 or better. ( B).
Application of Bayesian inference
For 300 hit for 1000
So for 30;for 100
Total ,330 for 1100
If we take the next 100 with respect to 1000 (base unchanged), it will be 0.330.
Bayesian inference is a statistical inference method that uses Bayes' theorem to update the probability of a hypothesis as new evidence or information becomes available. Bayesian inference is a crucial technique in statistics, particularly mathematical statistics. Bayesian updating is especially important in the dynamic analysis of a data sequence. Bayesian inference has been used in a variety of fields, including science, engineering, philosophy, medicine, sports, and law. Bayesian inference is closely related to subjective probability, which is often referred to as "Bayesian probability" in decision theory.

An urn contains 11 white balls and 5 green balls. A sample of seven is selected at random. What is the probability that the sample contains at least one green ball
The probbaility that the sample conatins at least one green ball is 0.90.
Let E be the event that denotes that the sample conatins at least one green.
According to the given question.
Total number of balls in an urn = 11 + 5 = 16
Total number of white balls = 11
Total number so green balls = 5
Now, the number of ways of selecting 7 balls from 16 balls
= \(^{16} C_{7}\)
= 16!/(7!9!)
= 11440
And the total number of ways of selecting 7 balls which contain atleast on green ball = \(^{11} C_{6} \times \ ^{5} C_{1} + ^{11} C_{5} \times \ ^{5} C_{2} + ^{11} C_{4} \times \ ^{5} C_{3} +^{11} C_{3} \times \ ^{4} C_{4}+^{11} C_{2} \times \ ^{5} C_{5}\)
= \(\frac{11!}{6!5!} \times \frac{5!}{1!4!} +\frac{5!}{2!3!} \times\frac{11!}{5!6!} +\frac{11!}{7!4!} \times\frac{5!}{3!2!} +\frac{11!}{8!3!} \times\frac{4!}{4!0!} +\frac{11!}{9!2!} \times\frac{5!}{0!5!}\)
= 452 × 5 + 10 × 452 + 330 × 10 + 165×1 + 55 ×1
= 2260 + 4520 +3300 + 165 + 55
= 10300
Thereofore, the probability that the sample conatins at least one green ball is given by
P(E) = (total number of ways of selecting 7 balls which contain atleast on green ball) / (the number of ways of selecting 7 balls from 16 balls )
⇒ P(E) = 10300/11440
⇒ P(E) = 0.90
Hence, the probbaility that the sample conatins at least one green ball is 0.90.
