 A sample mean, sample standard deviation, and sample size are given.

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 critical-value approach. x-bar = 3.26 , s = 0.55, n = 9, Ho : p = 2.85, H a : p > 2.85, a = 0.01 Assume that distribution of the variable in the parent population is normal. Choose the one alternative that best completes the statement or answers the question. 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. 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 = 0.1318. 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
