A sample mean, sample standard deviation, and sample size are given. Use the one-mean t-test to perform the required hypothesis test about the mean, u, of the population from which the sample was drawn. Use the P-value approach. Also, assess the strength of the evidence against the null hypothesis. Assume that the population is normally distributed. x bar = 137, s = 14.2, n - 20, Ho: u = 132, Ha: u + 132, a = 0.1 O Test statistic: t = 1.57. P-value = 0.1318. Do not reject Ho. There is not sufficient evidence to conclude that the mean is different from 132. The evidence against the null hypothesis is weak or none O Test statistic: t = 1.57. P-value = 0.0659. Reject Ho. There is sufficient evidence to conclude that the mean is different from 132. The evidence against the null hypothesis is moderate Test statistic: t = 1.57. P-value = 0.1164. Do not reject Ho. There is not sufficient evidence to conclude that the mean is different from 132. The evidence against the null hypothesis is weak or none O Test statistic: t = 1.57. P-value = 0.0582. Reject Ho. There is sufficient evidence to conclude that the mean is different from 132. The evidence against the null hypothesis is moderate
