Question

Problem 10.001 please help me find the solution to parts a b and c. show work please. Thanks!

	Your answer is partially correct. Try again.

Consider the hypothesis test against with known variances and Suppose that sample sizes and and that and Use

(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 if the true difference in means is 3? Assume that

(a) The null hypothesis

is notis

rejected. The P-value is . Round your answer to three decimal places (e.g. 98.765).

(b) The power is . Round your answer to two decimal places (e.g. 98.76).

(c) . Round your answer up to the nearest integer.
