A random sample of size 5 is drawn from a normal population. The five data items are 14.5, 14.2, 14.4, 14.3, and 14.6 Test the null hypothesis H0 : µ = 14.0 versus the alternative hypothesis Ha : µ 6= 14.0. Use an α = 0.05 test.

Using a random sample of size 77 from a normal population with variance of 1 but unknown mean, we wish to test the null hypothesis that H0: μ ≥ 1 against the alternative that Ha: μ <1. Choose a test statistic. Identify a non-crappy rejection region such that size of the test (α) is 5%. If π(-1,000) ≈ 0, then the rejection region is crappy. Find π(0).

A random sample is obtained from a population with a variance of σ2=200, and the sample mean is computed to be x̅c=60. Test if the mean value is μ=40. Test the claim at the 10% significance (α=.10). Consider the null hypothesis H0: μ=40 versus the alternative hypothesis H1:μ≠40 The distribution of the mean is normal N = 100.
