Transcribed Image Text:Consider the hypothesis test Ho : 41 = 42 against H1 :H # 42 with known standard deviations o = 11 and oz = 5. Suppose that
sample sizes nį = 10 and n2 = 15 and that I = 4.8 and F = 7.9. Use a = 0.05.
(a) Test the hypothesis and find the P-value.
(b) What is the power of the test in part (a) for a true difference in means of 3?
(c) Assuming equal sample sizes, what sample size should be used to obtain ß = 0.05 if the true difference in means is 3? Assume that
a = 0.05.
(a) The null hypothesis is not
rejected. The P-value is i
.Round your answer to three decimal
places (e.g. 98.765).
(b) The power is i
.Round your answer to two decimal places (e.g. 98.76).
(c) n1 = n2 =
. Round your answer up to the nearest integer.
