A boat capsized and sank in a lake. Based on an assumption of a mean weight of 132 lb, the boat was rated to carry 70 passengers (so the load limit was 9,240 lb). After the boat sank, the assumed mean weight for similar boats was changed from 132 Ib to 170 lb. Complete parts a and b below.

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 38 waves showed an average wave height of x = 16.7 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.   a) What is the value of the sample test statistic? (Round your answer to two decimal places.)
