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 the 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 pec lived. Partial results of the questionnaire are shown in the table below. 0-3 km distance 3 - 6 km distance 6 + km distance Totals Evacuation needed 54 Evacuation not XX

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? (  age  number of respondants  teenager  2468 young adult  14878 adult  8987 older adult  3678 A. all of the above  b. interval/ratio c. nominal  d. ordinal

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. (a) What is the level of significance?   State the null and alternate hypotheses. H0: ? = 16.4 ft; H1: ? ≠ 16.4 ft H0: ? > 16.4 ft; H1: ? = 16.4 ft     H0: ? < 16.4 ft; H1: ? = 16.4 ft H0: ? = 16.4 ft; H1: ? > 16.4 ft H0: ? = 16.4 ft; H1: ? <…

Hi please show step by step solution. Thank you!

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…

In tests of proportions, the data is qualitative. True False
