Problem 1E

Refer to Exercise 6 in Section 5.9. Let p represent the population mean compressive strength, in MPa.Consider the following null hypothesis:

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?
