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 ≥ 26, Ha: μ < 26, x=24.4 , s = 9.2, n = 25, α = 0.05 P-value = 0.8078. Do not reject H0. There is not sufficient evidence to conclude that the mean is less than 26. P-value = 0.8034. Do not reject H0. There is not sufficient evidence to conclude that the mean is less than 26. P-value = 0.1922. Do not reject H0. There is not sufficient evidence to conclude that the mean is less than 26. P-value = 0.1966. Do not reject H0. There is not sufficient evidence to conclude that the mean is less than 26
