Weatherwise is a magazine published by the American Meteorological Society. One issue gives a rating system used to classify Nor'easter storms that frequently hit New England and can cause much damage near the ocean. A severe storm has an average peak wave height of μ = 16.4 feet for waves hitting the shore. Suppose that a Nor'easter is in progress at the severe storm class rating. Peak wave heights are usually measured from land (using binoculars) off fixed cement piers. Suppose that a reading of 40 waves showed an average wave height of x = 16.9 feet. Previous studies of severe storms indicate that σ = 3.5 feet. Does this information suggest that the storm is (perhaps temporarily) increasing above the severe rating? Use α = 0.01. (a) What is the level of significance?State the null and alternate hypotheses. H0: μ = 16.4 ft; H1: μ < 16.4 ftH0: μ > 16.4 ft; H1: μ = 16.4 ft H0: μ < 16.4 ft; H1: μ = 16.4 ftH0: μ = 16.4 ft; H1: μ > 16.4 ftH0: μ = 16.4 ft; H1: μ ≠ 16.4 ft…

For n = 15 year-2017 model sedans whose horsepower is between 290 and 390, the following measurements give the time in seconds for the car to go from 0 to 60 mph: 4.8, 6.8, 6.0, 5.0, 6.3, 5.7, 5.8, 6.1, 5.5, 6.2, 4.9, 5.4, 5.1, 5.9, 5.6. The interval (Y1, Y7) could serve as a confidence interval for 1o.25. What is its confidence coefficient?
