# Question

Calculate the test statistic and p-value for each sample.

a. H0: μ = 60 versus H1: μ ≠ 60, α = .025 x-bar = 63, σ = 8, n = 16

b. H0: μ ≥ 60 versus H1: μ < 60, α = .025 x-bar = 58, σ = 8, n = 25

c. H0: μ ≤ 60 versus H1: μ > 60, α = .025 x-bar = 65, σ = 8, n = 36

a. H0: μ = 60 versus H1: μ ≠ 60, α = .025 x-bar = 63, σ = 8, n = 16

b. H0: μ ≥ 60 versus H1: μ < 60, α = .025 x-bar = 58, σ = 8, n = 25

c. H0: μ ≤ 60 versus H1: μ > 60, α = .025 x-bar = 65, σ = 8, n = 36
