# Question

Find the z calc test statistic for each hypothesis test.

a. x-bar = 242, μ0 = 230, σ = 18, n = 20

b. x-bar = 3.44, μ0 = 3.50, σ = 0.24, n = 40

c. x-bar = 21.02, μ0 = 20.00, σ = 2.52, n = 30

a. x-bar = 242, μ0 = 230, σ = 18, n = 20

b. x-bar = 3.44, μ0 = 3.50, σ = 0.24, n = 40

c. x-bar = 21.02, μ0 = 20.00, σ = 2.52, n = 30
