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 ? = 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 = 17.5 feet. Previous studies of severe storms indicate that ? = 4.0 feet. Does this information suggest that the storm is (perhaps temporarily) increasing above the severe rating? Use ? = 0.01. Solve the problem using the critical region method of testing (i.e., traditional method). (Round your answers to two decimal places.) test statistic = critical value = State your conclusion in the context of the application. Reject the null…

Peak wave heights are usually measured from land (using binoculars) off fixed cement piers. Suppose that a reading of 32 waves showed an average wave height of x = 17.3 feet. Previous studies of severe storms indicate that ? = 3.5 feet. Does this information suggest that the storm is (perhaps temporarily) increasing above the severe rating? Use ? = 0.01.
Lisa's scores on tests for the assessment class are 93, 89, 87, and 83. She needs an 89.5 average to obtain an "A" in the class. Assuming that all tests, including the final, are equally weighted, what score must she obtain on the final exam to earn an "A"? CA Vimsi l
Beanie babies are toy stuffed animals that have become valuable collector’s items. Beanie World Magazine provided the age, retired status (R for Retired and C for Current), and value of 50 Beanie babies. The data Beanie can be downloaded from Blackboard. Answer the following questions using Minitab. a) Show the retired/current status of the 50 Beanie babies with pie chart and bar chart. b) What percentage of the age measurements actually fall into ¯x±s, ¯x±2s, and ¯x±3s. Compare your result with the empirical rule
