Question
A researcher is interested in seeing if "practice makes perfect," or, at least if practicing basketball helps performance with free throws for high school basketball players at a particular high school. She takes a random sample of 5 basketball players and records how many free throws (out of 20) each player makes at the beginning of the season and how many free throws (out of 20) each player makes at the end of the season. The procedure most appropriate to analyze this data is:
One sample z test
One sample t test
Two sample t test
Matched pairs t test

A researcher is interested in determining if female high school basketball players are any better or worse at free throws than male highs school basketball players. He takes a random sample of 43 female high school basketball players and a random sample of 32 male high school basketball players and records how many free throws each student makes (out of 30). The researcher uses the appropriate test and all assumptions for the test are satisfied. He calculates a p-value of 0.17. What is the most appropriate conclusion?
There is strong evidence to say that males perform free throws at a different level than females do.
There is strong evidence that males and females perform free throws at the same level.
There is no evidence to say that males perform free throws at a different level than females do.
There is no evidence that males and females perform free throws at the same level.
Explanation / Answer
Answer - 16: Since the sample units are same in both the samples, the samples will be dependent and hence, we will use Matched Pair t test.
Option D is correct.
Answer - 17: Since we are comparing two independent populations here, we will use two sample t test.
Option C is correct.
Answer - 18: Option C is correct.
