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

A random sample n=30 is obtained from a population with unknown variance. The sample variance s2 = 100 and the sample mean is computed to be 85. Test the hypothesis at α = 0.05 that the population mean equals 80 against the alternative that it is more than 80. The null hypothesis Ho: µ = 80 versus the alternative H1: Ho: µ > 80. Calculate the test statistic from your sample mean. Then calculate the p-value for this test using...
