Refer to the data on the amount of reflected light from urban areas in Table D.3b of the Data Bank. A computer calculation for a test of H0: u = 84 versus H1: μ ‰  84 has the output
Test of mu = 84 vs mu not = 84

(a) What is the conclusion of the test when α = .03?
(b) Use the value for Z to test the null hypothesis H0: μ = 84 versus the one-sided alternative H1: μ
