The eight subjects used for this comparison were not a random sample. In fact, they were friends of the researchers whose ages and weights were similar to the types of people who would be measured with this DXA. Comment on the appropriateness of this procedure for selecting a sample, and discuss any consequences regarding the interpretation of the significance testing and confidence interval results.
Answers
Answer:
The sample may be a representative of the future of the future subjects, but the test results and confidence interval are suspect because it is not a random sample
Step-by-step explanation:
When the subjects used for a research are not a random sample but friends whom share similar qualities/quantities related to the purpose of the experiment. The sample may be a representative of the future subjects, but the test results and confidence interval will not be reliable enough to be accepted as standard simply because it was not a random sample
Hence the comment :The sample may be a representative of the future of the future subjects, but the test results and confidence interval are suspect because it is not a random sample
At the book fair, Vald spends all of his money on new books. Pamela spends
2/3 as much as Vald. Eli spends 4/3 as much as Vald. Who spent the most?
The least?
Answers
Step-by-step explanation:
Lets take Vald spends $100 on the book fair which are all the money he had.
Pamela Spends 2/3 as much as Vald
Pamela Spends 2/3 x 100 = $66.67
Eli Spends 4/3 as much as Vald
Eli spends 4/3 x 100 = $133.33
From here, we can see Eli Spends the most and Pamela Spends the least.
A computer engineer is investigating whether the amount of installed RAM (random access memory) can be used to predict the mean cost of a laptop with the operating system. The computer engineer collected a sample of 20 laptops with the same operating system. The engineer wants to estimate the mean change in the cost, in dollars, for each increase of 1 gigabyte of installed RAM. Assuming the conditions for inference have been met, which of the following inference procedures is the most appropriate for such an investigation?
a. A two-sample z-interval for a difference between proportions.
b. A two-sample t-interval for a difference between means.
c. A matched-pairs t-interval for a mean difference.
d. A one-sample t-test for means.
e. A linear regression t-interval for slope

Two Social Security numbers (see Exercise 8.12) match zeros if a digit of one number is zero iff the corresponding digit of the other is also zero. In other words, the zeros in the two numbers appear in exactly the same position. For example, the Social Security numbers 120-90-1109 and 430-20-5402 have matching zeros.
Prove: Given a collection of 513 Social Security numbers, there must be two that match zeros.
Answers
Answer:
Proved
Step-by-step explanation:
From the given parameters, we have:
[tex]n = 9[/tex] i.e. the length of each security numbers
[tex]r = 2[/tex] i.e. 2 security numbers
Required
In 513 security numbers, 2 must have matching zeros
To do this, we make use of Pigeonhole principle.
First, we calculate the number of all security numbers not having matching zeros.
Each of the 9 digits can be selected in 2 ways.
2 ways implies that each digit is either 0 or not
So, total selection is:
[tex]Total = 2^9[/tex]
[tex]Total = 512[/tex]
Apply Pigeonhole principle
The principle states that: suppose there are n items in m containers, where [tex]n>m[/tex], then there is at least one container that contains more than 1 item.
This means that if there are 512 security number without matching zeros, then there is 1 (i.e. 512 + 1) with matching zeros.
[tex]512 + 1 = 513[/tex]

Janie ordered boxed lunches for a student advisory committee meeting. Each lunch costs $4.25. The total cost of the lunches is $53.75, including a $7 delivery fee.
Part A
Which equation will help you find x, the number of boxed lunches Janie ordered?
a 4.25x = 60.75
b 4.25 + 7x = 53.75
c 4.25x + 7 = 53.75
d 4.25(x + 7) = 53.75
Part B
Solve the equation from Part A to find x.
x = _____
Answers
Answer:
Part A: c. 4.25x+7=53.75
Part B: 11
Step-by-step explanation:
4.25x+7=53.75
4.25x=46.75
x=11
You are planning on applying to the Knirhsdaeh institute as a psychology counselor. They hire millions of psychologists around the world. You know the standard deviation for the salaries is $13 k. To find the average, you sample 23 random employees and get an average salary of $81 k. Find an 98% confidence interval for the true average salary of Knirhsdaeh employees.
Answers
Answer:
The 98% of the confidence interval for the true average salary of Knirhsdaeh employees as a psychology counselor
(75.4206, 86.5794)
Step-by-step explanation:
Step(i):-
Given that the mean of the sample = $81 k
Given that the size of the sample 'n' = 23
Given that the standard deviation for the salaries is $13 k
Step(ii):-
98% of the confidence interval for the true average salary of Knirhsdaeh employees is determined by
[tex](x^{-} - t_{0.02} \frac{S.D}{\sqrt{n} } , x^{-} + t_{0.02} \frac{S.D}{\sqrt{n} })[/tex]
Degrees of freedom = n-1 = 23-1 =22
[tex]t_{0.02} = 2.5083[/tex]
[tex](81 - 2.0583 \frac{13}{\sqrt{23} } , 81 + 2.0583 \frac{13}{\sqrt{23} } )[/tex]
( 81 - 5.57940 , 81 + 5.57940)
(75.4206, 86.5794)
Final answer:-
The 98% of the confidence interval for the true average salary of Knirhsdaeh employees as a psychology counselor

Answer:
18°
Step-by-step explanation:
Angle ACD is the complement of the 18° angle shown, 72°. Arc AB is double that measure, so is 144°. Arc BE is the supplement to that, so is 36°. This is the arc subtended by inscribed angle BAE. That inscribed angle is half the measure of arc BE, so is 36°/2 = 18°.
angle BAE = 18°
