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 Assume that the population is normally distributed. x bar = 38.1, s = 8, n = 15, Ho : H - 32.6, Ha : H # 32.6, a = 0.05 O Test statistic: t = 2.66. Critical values: t = =2.145. Do not reject Ho: H = 32.6. There is not sufficient evidence to support the claim that the mean is different from 32.6 O Test statistic: t = 2.66. Critical values: t = #1.96. Reject Ho: p = 32.6. There is sufficient evidence to support the claim that the mean is different from 32.6. O Test statistic: t = 2.66. Critical values: t = #1.96. Do not reject Ho: u = 32.6. There is not sufficient evidence to support the claim that the mean is different from 32.6. O Test statistic: t = 2.66: Critical values: Reject Ho: H = 32.6. There is sufficient evidence to s he mean is different from 32.6
