Suppose you want to test the claim that a population mean equals 48.

(a)

State the null hypothesis.

H0: μ > 48H0: μ < 48    H0: μ = 48H0: μ ≠ 48H0: μ ≥ 48

(b)

State the alternate hypothesis if you have no information regarding how the population mean might differ from 48.

H1: μ > 48H1: μ < 48    H1: μ = 48H1: μ ≠ 48H1: μ ≥ 48

(c)

State the alternative hypothesis if you believe (based on experience or past studies) that the population mean may exceed 48.

H1: μ > 48H1: μ < 48    H1: μ = 48H1: μ ≠ 48H1: μ ≥ 48

(d)

State the alternative hypothesis if you believe (based on experience or past studies) that the population mean may be less than 48.

H1: μ > 48H1: μ < 48    H1: μ = 48H1: μ ≠ 48H1: μ ≥ 48
