- 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 u = 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 34 waves showed an average wave height of x = 16.7 feet. Previous studies of severe storms indicate that o = 3.5 feet. Does this information suggest that the storm is (perhaps temporarily) increasing above the severe rating? Use a = 0.01.Using the data below: timestamp Basel Wind Speed [10 m] 2022-12-20T00:00:00 18.681883 2022-12-21T00:00:00 35.652725 2022-12-22T00:00:00 37.11319 2022-12-23T00:00:00 37.57993 2022-12-24T00:00:00 23.157824 2022-12-25T00:00:00 15.807239 2022-12-26T00:00:00 24.923338 2022-12-27T00:00:00 23.664352 2022-12-28T00:00:00 16.75064 2022-12-29T00:00:00 26.009842 Calculate: Mean Median Mode Range Standard DeviationThe following table is a selection of average prices for a gallon of gas in the United States.
