Referring to Problem 1, test at the 5% level of significance: H0: μ = 800 versus H1:
μ != 800. What is the power of the test at μ = 795 and at μ = 805?

An existing process used to manufacture paint yields daily batches that have been
fairly well established to be
tons. A modification of this process is suggested with the view of increasing production. Assume that the daily yields, using the modified process, are distributed
as N(μ,(30)2), and suppose that a sample taken on 100 randomly chosen days of
production using the modified process yields an average of X¯ = 812 tons. Test at the
1% level of significance H0: μ = 800 versus H1: μ > 800. What is the power of the
test at μ = 810? Graph the power
