A group of 100 people, who lived at varying distances (in kilometers) from an island nuclear power station, were asked if they thought a full evacuation ofthe area was required, when it went critical. The researches wanted to know if the opinion to evacuate or not depended on how far from the reactor peoplelived,Partial results of the questionnaire are shown in the table below.0-3 km distance 3 -6 km distance 6 + km distance TotalsEvacuation neededXXX54Evacuation notXXXneededTotals3332XXXXYou are doing a Chi Square test for independence. XX denotes row/column totals. Compute the expected number of people living 6+km away whowould prefer NOT to evacuate. Give your answer to 2 decimal places.

Given that there are 100 people. Therefore, the table becomes, 0-3 km distance 3-6 km distance…

A researcher wonders whether younger mothers have babies that are significantly heavier or lighter than the population average of μ 7.25 pounds. The researcher collects data from N = 35 babies who were born to mothers between the ages of 16 and 18. The average weight for these babies was M = 7.15 pounds (SD = .6 pounds).
A survey is conducted at a community college and respondents are asked to disclose their age. The results have been included below. Based on this, a variable called "Age" would be considered?

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 35 waves showed an average wave height of x = 17.3 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.

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 = 17.4 feet. Previous studies of severe storms indicate that ? = 3.0 feet. Does this information suggest that the storm is (perhaps temporarily) increasing above the severe rating? Use ? = 0.01. Solve the problem using the critical region method of testing (i.e., traditional method). State the null and alternative hypotheses (in feet). (Enter != for ≠ as needed.) Calculate the appropriate test statistic. (Round your answer to two decimal…
