According to the National Coffee Drinking Study from the National Coffee Association, 40% of 18- to 24-year-olds in the U.S.regularly drink coffee every day. Suppose this number is accurate. In a sample of 140 students at Hope College we found that 63 of them (or 45%) regularly drink coffee. We want to test whether the daily coffee-drinking habits of students at Hope College differ from the 40% claim for the nation. Which of A - E is an appropriate way to set up the hypotheses, in symbols, for the test?
A) H0 : p-hat = .4; Ha: p-hat =.4
B) H0 : = .4; Ha: =.4
C) H0 : p-hat = .45; Ha: p-hat =.45
D) H0 : = .45; Ha: =.45
E)H0 : = .4; Ha: >.4
