Consider the hypothesis test H0: μ1= μ2 against H1: μ1.Suppose that the sample sizes aren1 = 15 and n2 =μ2. Assume thatσ21 = σ22
andthat 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 confidenceinterval.
(c) What is the power of the test in part (a) for a truedifference in means of 3?
(d) Assuming equal sample sizes, what sample size should beused to obtain β = 0.05 if the true difference in means is -2?Assume that α = 0.05.

Answer:
The domain is .
Step-by-step explanation:
Domain is the input to a function. The input to a function is marked along the x axis as the x values are the independent values and thus are in the domain of the function.
From the graph, the function starts at when the point is (3,1) and then the graph of the moves towards infinity.
So, the domain of the function starts at 3 and move towards infinity.
Hence, the domain include the values between 3 to infinity including 3.
