A simple random sample was taken to test the claim that the population mean is no more than 125.

(a) What was the original claim?

μ ≠ 125μ ≥ 125    μ ≤ 125μ < 125μ = 125μ > 125


(b) What was the null hypothesis?

H0: μ ≠ 125H0: μ > 125    H0: μ ≥ 125H0: μ ≤ 125H0: μ < 125H0: μ = 125


(c) What was the alternative hypothesis?

H1: μ < 125H1: μ = 125    H1: μ ≥ 125H1: μ ≠ 125H1: μ > 125H1: μ ≤ 125
