: 3. Consider the hypothesis test IIo : 11 = 12 against II1:41 + H2 with known standard deviations 0 10 and 02 = 5. Suppose that samplesizes 1; = 10 and 112 = 15 and that I = 4.7 and D2 = 7.8. Use a = 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 part (a) if the true difference in means is 42 – M1 = 3? (d) Assume that sample sizes are equal. What sample size should be used to obtain 3 = 0.05 if the true difference in means is 3? Assume that o=0.05.
