Refer to Exercise 6 in Section 5.10. 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 5.10, which of these null hypotheses can be rejected at the 5% level if a confidence interval is formed using method 1 on page 390?

b. Using the bootstrap data presented in Exercise 6 in Section 5.10, which of these null hypotheses can be rejected at the 10% level if a confidence interval is formed using method 1 on page 390?

Refer to Exercise 6

In Example 5.20 (in Section 5.3) the following measurements were given for the cylindrical compressive strength (in MPa) for 11 beams:

Method 1:
