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 38 waves showed an average wave height of x = 16.7 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 value of the sample test statistic? (Round your answer to two decimal places.)

A national military bureau for a certain country collects data on active members in the military. Results are published in a national journal. According to the document, 75.4% of military members are in the reserves and 10.4% of military members are Black and in the reserves. What percentage of military members in the reserves are Black? Roughly % of military members in the reserves are Black. (Type an integer or a decimal. Round to one decimal place as needed.) View an example Get more help.

Certain car manufacturers install a gauge that tells the driver how many miles they can drive until they will run out of gas. A study was conducted to test the accuracy of these gauges. Each driver was assigned a certain gauge reading until empty to watch for. When their car announced it had that many miles remaining until empty, they began to measure their distance traveled. After they ran out of gas, they reported the distance they were able to drive (in miles) as well as the gauge reading they were assigned (in miles). Here is computer output showing the regression analysis: Identify and interpret the slope of the regression line used for predicting the actual distance that can be driven based on the gauge reading. (A) Slope = 1.1889. The predicted distance the drivers were able to drive increases by 1.1889 miles for each additional mile reported by the gauge. (B) Slope = 0.0457. The predicted distance the drivers were able to drive increases by 0.0457 miles for each additional…
Researchers investigated the effect of weed-killing herbicides on house pets. They examined 822 dogs from homes where herbicides were used regularly, diagnosing malignant lymphoma in 475 of them. Of the 125 dogs from homes where no herbicides were used, only 15 were found to have lymphoma. Complete parts a through c. a) What is the standard error of the difference in the two proportions?

A university conducted a study of online adults that included 411 tablet owners. The study found that 217 tablet owners use their tablet while watching TV. The authors of the report imply that the survey proves that more than half of all tablet owners use their tablet while watching TV at least once per day. Determine the p-value. The p-value is _______ (Round to four decimal places as needed.)
