Subset 3 - The next questions are based on the following information: The U.S. Postal Service advertises that at least 63.4% of all third class mail is read by the recipients. An environmental group, concerned about waste production wants to test this assertion. They take a sample of 220 households and find that only 58.7% read their third class mail. What are the null and alternative hypotheses for the environmental group's test? Select one: O a. Ho: P> 0.634 and H₁: P≤0.634 b. Ho: P = 0.634 and H₁: P<0.634 O C. Ho: P = 0.634 and H₁: P=0.634 O d. Ho: P = 0.634 and H₁: P>0.634 Clear my choice What would the environmental group's decision rule be? Select one: O a. Reject Ho if (P - Po) / √P (1 − P) / n <-za/2 b. Reject Ho if (P-Po)/√Po (1 − Po) / n >-²a/2 O c. Reject Ho if (P – Po)/√√Po (1 - Po)/n <-²α O d. Reject Ho if (P-Po)/√Po (1-Po)/n >-Za Which of the following statements is most accurate? Select one: a. Reject the null hypothesis at a = 0.01 b. Reject the null hypothesis at a = 0.10 O c. Reject the null hypothesis at a = 0.05 d. Fail to reject the null hypothesis at a ≤ 0.10
