Consider the hypothesis test H0:μ1=μ2 against H1:μ1<μ2. Suppose the sample sizes are n1=n2=15, that x1=6.2 and x2=7.8and that s21=4 and s22=6.25. Assume that σ21=σ22 and the data are drawn from normal distributions. Use α=0.05.. a) Test the hypothesis and find the p-value. b) Explain how the test could be conducted with a confidence interval. c)What is the power of the test in pair a) if μ1 is three unit less than μ2?
