Unformatted text preview: that the true average number of seconds it takes to reach 60 mph from zero is above 5.0. Suppose the population standard deviation is believed to be 0.43 seconds. We wish to test H : μ ≤ 5.0 vs. H 1 : μ > 5.0. Find the power of this test if the true average time is 5.15 seconds, a 5% level of significance will be used, and 50 automobiles will be tested (each automobile to be tested a single time). 3. Suppose n = 49 observations are taken from a normal distribution where σ = 8.0 for the purpose of testing H : μ = 60 versus H 1 : μ ≠ 60 at the α = 0.05 level of significance. What is the power of the appropriate test when μ = 59.2?...
