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 39 waves showed an average wave height of x = 17.4 feet. Previous studies of severe storms indicate that σ = 3.0 feet. Does this information suggest that the storm is (perhaps temporarily) increasing above the severe rating? Use α = 0.01. Solve the problem using the critical region method of testing (i.e., traditional method). (Round your answers to two decimal places.) test statitics= critical=Forty plasma TVs were tested, and the number of watts per hour they used recorded. Given that the values ranged from a low of 435 to a high of 503, calculate the width to be used in the construction of a frequency distribution for the data with 6 classes. To find the width, find the difference between the highest and lowest data values, divide by the number of classes, and round up to the next odd number.
