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. , , n = 15, H0: μ = 32.6, Ha: μ ≠ 32.6, α = 0.05. Test statistic: t = 2.66. Critical values: t = ±2.145. Reject H0. There is sufficient evidence to support the claim that the mean is different from 32.6. Test statistic: t = 2.66. Critical values: t = ±1.96. Reject H0. There is sufficient evidence to support the claim that the mean is different from 32.6. Test statistic: t = 2.66. Critical values: t = ±1.96. Do not reject H0. There is not sufficient evidence to support the claim that the mean is different from 32.6. Test statistic: t = 2.66. Critical values: t = ±2.145. Do not reject H0. There is not sufficient evidence to support the claim that the mean is different from 32.6.
