Find the z calc test statistic for each hypothesis test.

a. x-bar = 423, μ0 = 420, σ = 6, n = 9

b. x-bar = 8330, μ0 = 8,344, σ = 48, n = 36

c. x-bar = 3.102, μ0 = 3.110, σ = .250, n = 25

a. x-bar = 423, μ0 = 420, σ = 6, n = 9

b. x-bar = 8330, μ0 = 8,344, σ = 48, n = 36

c. x-bar = 3.102, μ0 = 3.110, σ = .250, n = 25
