Chapter 9.4, Problem 25E

Consider the following hypothesis test:

 H₀: μ ≥ 45

 H_a: μ < 45

A sample of 36 is used. Identify the p-value and state your conclusion for each of the following sample results. Use α = .01.

1. a. $\bar{x}$ = 44 and s = 5.2
2. b. $\bar{x}$ = 43 and s = 4.6
3. c. $\bar{x}$ = 46 and s = 5.0
