Suppose we wish to test the hypothesis that an internship program allows its interns to earn $2,750 per semester and let us assume that this hypothesis is, in fact, true. Which of the following best illustrates the logic of hypothesis testing at the 95% confidence level?
A) From among 100 samples, 95 percent of them would generate means that fell within + 1.96 z scores.
B) From among 100 samples, 98 percent of them would generate means that fell within + 2.58 z scores.
C) From among 100 samples, 95 percent of them would generate means that fell within + 2.58 z scores.
D) From among 100 samples, 99 percent of them would generate means that fell within + 1.96 z scores.
E) From among 95 samples, 100 percent of them would generate means that fell within + 1.96 z scores.
