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 32 waves showed an average wave height of x = 17.0 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. Solve the problem using the critical region method of testing (i.e., traditional method). (Round your answers to two decimal places.) test statistic =| critical value =| State your conclusion in the context of the application. O Reject the null hypothesis, there is sufficient evidence that the average storm level is increasing. O Reject the null hypothesis, there is insufficient evidence that the average storm level is increasing. O Fail to reject the null hypothesis, there is sufficient evidence that the average storm level is increasing. O Fail to reject the null hypothesis, there is insufficient evidence that the average storm level is increasing. Compare your conclusion with the conclusion obtained by using the P-value method. Are they the same? O we reject the nll hypothesis using the traditional method, but fail to reject using the P-value method. O We reject the nll hypothesis using the P-value method, but fail to reject using the traditional method. O The conclusions obtained by using both methods are the same.

Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.

Question
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 = 16.4 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 32 waves showed an average wave height of x = 17.0 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. Solve the problem using the critical region method
of testing (i.e., traditional method). (Round your answers to two decimal places.)
test statistic =
critical value =
State your conclusion in the context of the application.
O Reject the null hypothesis, there is sufficient evidence that the average storm level is increasing.
O Reject the null hypothesis, there is insufficient evidence that the average storm level is increasing.
O Fail to reject the null hypothesis, there is sufficient evidence that the average storm level is increasing.
O Fail to reject the null hypothesis, there is insufficient evidence that the average storm level is increasing.
Compare your conclusion with the conclusion obtained by using the P-value method. Are they the same?
O we reject the nll hypothesis using the traditional method, but fail to reject using the P-value method.
O We reject the null hypothesis using the P-value method, but fail to reject using the traditional method.
O The conclusions obtained by using both methods are the same.
