Given that the mean female buttock-popliteal length in the company is490.5 mm (SD 33.2 mm), what percentage of the company's femaleworkers will be able to sit on the seats without having to adopt a posturein which they are perched or hanging on the edge of the seat? You decidethat seat depth is a critical factor. The company has a shortlist of 14 chairsbut none of them has adjustable seat depth. You measure the depth of theseats with the following results: *Seat Depth(mm)Number of Chairs at theDepth4503420400339037030.760.670.87None of These.

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.)

In the vertical-horizontal line illusion, the two lines are exactly the same length, but the vertical line appears to be much longer. To examine the strength of this illusion, a researcher prepared an example in which both lines were exactly 10 inches long. The example was shown to individual participants who were told that the horizontal line was 10 inches long and then were asked to estimate the length of the vertical line. For a sample of n = 25 participants, the average estimate was M = 12.2 inches with a standard deviation of s = 1.00. Calculate t statistic.
