Don't know how to solve

Transcribed Image Text: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 = 16.3 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 a
large random sample of 37 waves showed an average wave height of 17.5 feet. Previous studies of
severe storms indicate that a = 3.4 feet.
Does this information suggest that the storm has (perhaps temporarily) more wave height? Use x =
0.05. Round answers to 4 decimals where possible.
1. Determine the null and alternative hypotheses. Fill in one blank for Ho and 2 blanks for Ha
H₁:μ =
H₁:μ?v
2. The Test Statistic type
To 4 decimal places, the Test Statistic amount =
To 4 decimal places, the p-value =
3. For the rejection region, the critical value type
To 4 decimal places, the critical value amount =
Make a decision using the rejection region method.
O Reject the null hypothesis.
O Fail to reject the null hypothesis.
4. Is the p-value greater or less than a? ?
