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:
Ming must add 0.375 L of a 10% sugar solution
Step-by-step explanation:
if 3 L = 80%
1.5 L should = 40% (since it is half of 80%)
and if 40 divided by 4 = 10%
1.5 also needs to be divided by 4
so 1.5 divided by 4 = 0.375
that means Ming must add 0.375 L of a 10% sugar solution

Step-by-step explanation:
Given that a random sample of records of home sales from Feb. 15 to Apr. 30, 1993, from the files maintained by the Albuquerque Board of Realtors gives the Price and Size (in square feet) of 117 homes.
A regression is done to predict Price (in thousands of dollars) from Size
Hence
a)we have size as independent variable and price as dependent variable. Units for size are square feet and price are in 1000s of dollars.
b) Slope will have unit has 1000dollar/sqft
c) Slope is positive since price is directly variant over size.
So slope will be positive.
