We are given that n=15, the sample mean Ῡ=2.5, the sample standard deviation s=1.5 and random variable Y distributed Normal with mean µ and variance σ2, where both µ and σ2 are unknown and we are being concentrated on testing the following set of hypothesis about the mean parameter of the population of interest.

We are to test:

H0 : µ ≥ 3.0 versus H1 : µ < 3.0.

Compute the following:

a) P- value of the test

b)    Probability of making Type II error and the power of this test at µ= 2.0

From a random sample from normal population, we observed sample mean=84.5 and sample standard deviation=11.2, n = 16, H0: μ = 80, Ha: μ < 80.  State your conclusion about H0 at significance level 0.01. choices: A. Test statistic: t = 1.61. P-value = 0.9356. Reject the null hypothesis. There is sufficient evidence to conclude that the mean is less than 80. The evidence against the null hypothesis is very strong. B. Test statistic: t = 1.61. P-value = 0.0644. Do...
