The results of a paired-difference test are shown below to the right. d = 5.6
a. Construct and interpret a 99% confidence interval estimate for the paired difference Sd =0.25 in mean values.
b. Construct and interpret a 90% confidence interval estimate for the paired difference n=16 in mean values_ (Round to two decimal places as needed:) Choose the correct answer below:
OA This interval will contain the true population mean 90% of the time_
OB. There is a 90% chance that the true population mean is contained in the interval.
Oc: If many random samples of this size were taken and intervals constructed, 90% of them would contain the true population mean: 0
D. Approximately 90% of the differences will be contained in the interval.
Answers
If many random samples of this size were taken and intervals constructed, 90% of them would contain the true population mean. In repeated sampling, about 90% of the constructed confidence intervals will capture the true population mean difference. The correct answer is C.
When we construct a confidence interval, it is important to understand its interpretation. In this case, the correct answer (Oc) states that if we were to take many random samples of the same size and construct confidence intervals for each sample, approximately 90% of these intervals would contain the true population mean difference.
This interpretation is based on the concept of sampling variability. Due to random sampling, different samples from the same population will yield slightly different sample means.
The confidence interval accounts for this variability by providing a range of values within which we can reasonably expect the true population mean difference to fall a certain percentage of the time.
In the given scenario, when constructing a 90% confidence interval for the paired difference, it means that 90% of the intervals we construct from repeated samples will successfully capture the true population mean difference, while 10% of the intervals may not contain the true value.
It's important to note that this interpretation does not imply a probability or chance for an individual interval to capture the true population mean. Once the interval is constructed, it either does or does not contain the true value. The confidence level refers to the long-term behavior of the intervals when repeated sampling is considered.

Simon ran a 50 yard dash in 7.02 seconds and Tony ran a 200 yard dash into 24.19 seconds who run faster?
Answers
Answer: Tony
Step-by-step explanation: What I did is I took the 7.02 and multiplied it by 4 to make the 50 200 and I got 28.08 so since the time for Simon is larger than the time for Tony, tony went faster because it look him less time. Hope this helps!
Answer: Tony was faster
Step-by-step explanation: To find who ran faster we multiply Tony's time by 4. If it took Tony 7.02 seconds for 50 yards we can multiply that by for to find how long it would have taken him at that speed to run 200 yards.

Write a polynomial function of least degree with integral coefficients that has the given zeros
Answers
The polynomial function of least degree with integral coefficients is equal to f(x) = x³ - 4x² + x + 6 with the given zeros 3, 2, -1.
As given in the question,
Given zeros of the polynomial function are :
3, 2, -1
⇒ ( x - 3 ) =0 or ( x - 2 ) = 0 or ( x + 1 ) = 0
Polynomial function of the given factors ( x - 3 ) =0 or ( x - 2 ) = 0 or
( x + 1 ) = 0 is given by :
f (x ) = ( x - 3 )( x - 2 )( x + 1 )
⇒ f(x) = ( x² - 3x - 2x + 6 ) ( x + 1 )
⇒ f(x) = ( x² - 5x + 6 ) ( x + 1 )
⇒ f(x) = x³ + x² -5x² - 5x + 6x + 6
⇒f(x) = x³ - 4x² + x + 6
Therefore, the required polynomial function of least degree with integral coefficients using given zeros is equal to f(x) = x³ - 4x² + x + 6.

Find the range, the standard deviation, and the variance for the given samples. Round non-integer results to the nearest tenth.−10, −16, −21, −24, −4, −30, −32 range ________standard deviation __________variance __________
Answers
From the given values, we can see that the lowest values is -32 and the highest value ie -4. Since the range is the difference betwwwn the highest and the lowest value, the range is
\(\begin{gathered} \text{Range}=-4-(-32) \\ \text{Range}=28 \end{gathered}\)On the other hand, the sample variance formula is
\(S^2=\sqrt[]{\frac{\sum ^7_{n\mathop=1}(x-\bar{x})^2}{n-1}}\)where x^bar is the mean and n is the total number of sample elements. In our case, n=7 and the mean is

The value of the expression is -45.
An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
-5 |x - 1|
Substitute x = -8
= -5 |-8 - 1 |
= -5 x |-9|
= -5 x 9

Identify the type I error and the type II error that correspond to the given hypothesis.
The percentage of households with Internet access is greater than 60 %.
Answers
Answer: Type I error and Type II error are associated with hypothesis testing, where we test a hypothesis by collecting data and analyzing it.
For the given hypothesis, we can set up the null hypothesis as follows:
H0: The percentage of households with Internet access is less than or equal to 60%.
And the alternative hypothesis as:
Ha: The percentage of households with Internet access is greater than 60%.
Now, a Type I error occurs when we reject the null hypothesis (i.e., conclude that the percentage of households with Internet access is greater than 60%) when it is actually true. This means that we would be making a false claim that the percentage of households with Internet access is greater than 60%, when it is not.
On the other hand, a Type II error occurs when we fail to reject the null hypothesis (i.e., conclude that the percentage of households with Internet access is less than or equal to 60%) when it is actually false. This means that we would be missing the truth that the percentage of households with Internet access is greater than 60%.
So, in the context of the given hypothesis, a Type I error would be to conclude that the percentage of households with Internet access is greater than 60% when it is actually less than or equal to 60%, and a Type II error would be to fail to conclude that the percentage of households with Internet access is greater than 60% when it is actually greater than 60%.

you are playing a game of hide - and - seek with two friends . while one of your friends counts , you and your other friend are given a chance to hide in one of five possible hiding spots . you are each allowed to pick a hiding spot , and are permitted to share a hiding spot . your friend finishes counting and checks one of the five hiding spots . assuming that everyone's decisions are made uniformly at random , what are the chances that your friend does not find anyone in the first spot that they check ?
Answers
The probability the friend finds no one in the first spot is 60%.
What is probability?Probability is the chance or likelihood that an expected event occurs when there are many possible outcomes or events.
For instance, the probability that when the counting friend goes to the hiding spot, they can or cannot find a friend there.
The two friends can only hide in 2 spots, leaving 3 spots with nobody.
The number of hiding spots = 5
The number of friends hiding = 2
The number of counting friends = 1
The number of spots they can hide = 2 out of 5
The probability of finding a person in a hiding spot = 2/5 or 40%
The probability of not finding a person in a hiding spot = 3/5 (1 - 2/5) or 60% (1 - 40%).
The chances that your friend finds anyone in the first spot are 60%.

10201 germ have queued up for an attack uch that the number of queue i equal to the number of germ in each queue. Find the number of germ in each queue
Answers
There are 101 soldiers are on each line which is queued up for an attack.
Define the term square of the number?When a number is multiplied by itself, the result is a square number. For instance, 25 is a square number since it is composed of 5 lots of 5, or 5 × 5.The data given in question is-
10201 soldiers are present.
They are lined up so that the quantity of lines equals the quantity of soldiers in each line;
Let n = q number of queues.
Thus, if the number of lines is equal to the number of soldiers in each Q,
Then ;
q × q = 10201
q^2 = 10201
multiply both sides by their square root;
q = √10201
q = 101
Thus, 101 soldiers are on each line which is queued up for an attack.

Answers
The question presents the velocity and acceleration vectors of an object at a certain instant. The choices given include options related to the object's motion, such as speeding up, slowing down, moving in a straight line, or following a curved path.
To analyze the motion of the object based on the given velocity and acceleration vectors, we need to consider the relationship between these vectors. If the velocity and acceleration vectors have the same direction, the object is either speeding up or moving in a straight line. If they have opposite directions, the object is either slowing down or following a curved path.
Looking at the given vectors, the velocity vector v has a magnitude of 3.0 m/s and points in the y-direction (ʀ^). The acceleration vector a has a magnitude of 0.5 m/s² and points in the x-direction (ɨ^), with a component in the negative y-direction (-0.2 m/s²). Since the velocity and acceleration vectors have different directions (ʀ^ and ɨ^), the object is slowing down and following a curved path.
Therefore, the correct answer is (C) slowing down and following a curved path.
