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 37 waves showed an average wave height of x = 16.5 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.

Suppose the doctors at a local office take a health survey of 100 adult female patients with similar weight who have had appointments in the last week. According to their medical file, the 100 participants all weigh between 140 – 149 lbs. One of the survey questions asks participants to list their current weight. The accompanying tables show the relative frequency of weights measured by the physician for the 100 participants and the relative frequency of weights recorded in the survey for the 100 participants. Note that some of the weights reported in the survey did not fall between 140 – 149 lbs. Weights reported by physician (to the nearest pound) Weights recorded by participants Weight (in pounds) Relative frequency Weight (in pounds) Relative frequency 140 0.12 140 0.32 141 0.09 141 0.04 142 0.17 142 0.05 143 0.06 143 0.04 144 0.14 144 0.07 145 0.11 145 0.23 146 0.04 146 0.01 147 0.10 147 0.01 148 0.09 148 0.03 149 0.08 149 0.02 Total 1.00 Total 0.82 Select the statements that are…

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 dass rating. Peak wave heights are usually measured from land (using binoculars) off foxed cement piers. Suppose that a reading of 36 waves showed an average wave height of x- 16.9 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 a - 0.01. (a) What is the level of significance? O State the null and alternate hypotheses. O H: - 16.4 ft; H,: > 16.4 ft O Ho H 16.4 t; H,: - 16.4 m (b) What sampling distribution will you use? Explain the rationale for your choice of sampling distribution. O The standard…

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.
