Reconsider Exercises 1.2.9 and 1.2.10 about your friend shooting free throws. You run this test and find a p-value of 0.1150. Which of A–E is the best way to state the conclusion? 

A. Because the p-value is large, there is strong evidence that your friend is a 75% free-throw shooter in the long run. 

B. Because the p-value is not small enough, there is not strong evidence that your friend is less than a 75% free-throw shooter in the long run. 

C. Because the p-value is small, there is strong evidence that your friend is less than a 75% free-throw shooter in the long run. 

D. Because the p-value is small, there is strong evidence that your friend is a 75% free-throw shooter in the long run. E. Because the p-value is large, there is strong evidence that your friend is a 65% free-throw shooter in the long run 


Data from Exercises 1.2.9

Suppose a friend of yours says she is a 75% free-throw shooter in basketball. You don’t think she is that good and want to test her to gather evidence that she makes less than 75% of her free throws in the long run. You have her shoot 40 free throws and she makes 26 (or 65%) of them. Which of A–E is an appropriate way to set up the hypotheses, in symbols, for this test?
