Chapter 19, Problem 10E

More critical values For each of the following situations, find the critical value for z or t.

a) H₀: μ = 105 vs. H_A: μ ≠ 105 at α = 0.05; n = 61.

b) H₀: p = 0.05 vs. H_A: p > 0.05 at α = 0.05.

c) H₀: p = 0.6 vs. H_A: p ≠ 0.6 at α = 0.01.

d) H₀: p = 0.5 vs. H_A: p < 0.5 at α = 0.01; n = 500.

e) H₀: p = 0.2 vs. H_A: p < 0.2 at α = 0.01.
