The doctor computed test statistic to test his claim that the average body temperature is less than 98.6 degrees Fahrenheit.
Test statistic is a statistic which is derived from the sample to test whether to accept the null hypothesis or accept the null hypothesis. As we have been given in the question the doctor wanted to test his claim, so he did a hypothesis test. And for the hypothesis test he calculated a random from the sample that was collected from the population data which is known as the test statistic.
Hence doctor computed the test statistic to test his claim.

Answer:
This means that, when the price of book from publisher is $60, the bookstore will sell it $88 to the students.
Step-by-step explanation:
Solution:
The cost of book from publisher = 40%
Sales tax = 7.5%
Price of books to the student = p(x) = 1.075x + 0.40x
Where, x is cost of book.
P (60) =?
We know that,
P(x) = 1.075 + 0.40
= 1.475%
=148
Given, Cost of book, x = 60
P (60) = 148 – 60
= 88
This means that, when the price of book from publisher is $60, the bookstore will sell it $88 to the students.
Answer:
Step-by-step explanation:
9/2 / 8/3
9/2 x 3/8
27/16 = 1 13/16
<h3>
Answer: 55 minutes</h3>
Work Shown:
(12 pictures)/(5 minutes) = (132 pictures)/(x minutes)
12/5 = 132/x
12x = 5*132
12x = 660
x = 660/12
x = 55
Note: I used the cross multiplication rule in the third step.
