Reconsider the scenario in Exercise 1.4.4 about coffee consumption. Which of AE is the appropriate sample statistic

Question:

Reconsider the scenario in Exercise 1.4.4 about coffee consumption. Which of A–E is the appropriate sample statistic and proper symbol?

A. p̂ = 0.40

B. π = 0.40

C. p̂ = 0.45

D. π = 0.45

E. n = 140

Data from Exercises 1.4.4

According to the National Coffee Drinking Study from the National Coffee Association, 40% of 18- to 24-year-olds in the United States 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 this test?
