A sample mean, sample standard deviation, and sample size are given. Use the one meant test to perform the required hypothesis test about the mean, , 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. x-22,298, s=14200, n = 17, HO: P = 30,000, Ha# 30,000 a -0.05. Test statistic: 224. P.value 0.0200. Reject the null hypothesis. There is sufficient evidence to conclude that the...

A random sample from normal population yielded sample mean=40.8 and sample standard deviation=6.1, n = 15. HO: u = 32.6, Haru # 32.6, a = 0.05. Perform the hypothesis test and draw your conclusion. Test statistic: t = 5.21. P-value=1.9E-7 (0.00000019). Reject Ho. There is sufficient evidence to support the claim that the mean is different from 32.6. Test statistic: t = 5.21. P-value=1.9E-7 (0.00000019). Do not reject HO. There is not sufficient evidence to support the claim that the...
