Question

A sample mean, sample standard deviation, and sample size are given. Perform the required hypothesis test about the mean, μ, of the normal population from which the sample was drawn.

H₀: μ = 132, H_a: μ ≠ 132,

x=137 , s = 14.2, n = 20, α = 0.10

		P-value = 0.0582. Reject H₀. There is sufficient evidence to conclude that the mean is different from 132.
		P-value = 0.0659. Reject H₀. There is sufficient evidence to conclude that the mean is different from 132.
		P-value = 0.1318. Do not reject H₀. There is not sufficient evidence to conclude that the mean is different from 132.
		P-value = 0.1164. Do not reject H₀. There is not sufficient evidence to conclude that the mean is different from 132.
