Refer to Exercise 6 in Section 5.9. Let represent the population mean compressive strength, in MPa.

Question:

Refer to Exercise 6 in Section 5.9. Let μ represent the population mean compressive strength, in MPa. Consider the following null hypotheses:
i. H0 : μ = 38.53
ii. H0 : μ = 38.35
iii. H0 : μ = 38.45
iv. H0 : μ = 38.55
a. Using the bootstrap data presented in Exercise 6 in Section 5.9, which of these null hypotheses can be rejected at the 5% level if a confidence interval is formed using method 1 on page 386?
b. Using the bootstrap data presented in Exercise 6 in Section 5.9, which of these null hypotheses can be rejected at the 10% level if a confidence interval is formed using method 1 on page 386?
