7. Suppose you are testing H0 : µ = 10 vs H1 : µ 6= 10. The sample is small (n = 5) and the data come from a normal population. The variance, σ 2 , is unknown. (a) Find the critical value(s) corresponding to α = 0.10. (b) You find that t = −1.78. Based on your critical value, what decision do you make regarding the null hypothesis (i.e. do you Reject H0 or Do Not Reject H0)?

You are testing H0: µ1 - µ 2 = 0 vs H1: µ1 - µ2 ≠ 0. In doing so, you are choosing n1 observations from population 1, and n2 observations from population 2. Keeping the same total N = 100 = n1 + n2, compute the power of the test to detect a difference of 0.6, with a population standard deviation of 1.0 when: n1 = 0.1×n2, n1 = 0.2×n2, n1 = 0.3×n2, …, n1 = 1.0×n2, n1 =...
