According to the N.Y. Times Almanac the mean family size in the U.S. is 3.18. A sample of a college math class resulted in the following family sizes:

5;4;5;4;4;3;6;4;3;3;5;5;6;3;3;2;7;4;5;2;2;2;3;2

At 伪=0.05 level, is the class鈥� mean family size greater than the national average? Does the Almanac result remain valid? Why?

The mean throwing distance of a football for Marco, a high school freshman quarterback, is 40yards, with a standard deviation of two yards. The team coach tells Marco to adjust his grip to get more distance. The coach records the distances for 20throws. For the 20throws, Marco鈥檚 mean distance was 45yards. The coach thought the different grip helped Marco throw farther than 40yards. Conduct a hypothesis test using a preset 伪=0.05. Assume the throw distances for footballs are normal.

First, determine what type of test this is, set up the hypothesis test, find thep-value, sketch the graph, and state your conclusion.

An article in the San Jose Mercury News stated that students in the California state university system take 4.5 years, on

average, to finish their undergraduate degrees. Suppose you believe that the mean time is longer. You conduct a survey of

49students and obtain a sample mean of 5.1with a sample standard deviation of 1.2Do the data support your claim at the

In 1955, Life Magazine reported that the 25year-old mother of three worked, on average, an 80 hour week. Recently,

many groups have been studying whether or not the women's movement has, in fact, resulted in an increase in the average

work week for women (combining employment and at-home work). Suppose a study was done to determine if the mean

work week has increased. 81women were surveyed with the following results. The sample mean was83the sample

standard deviation was ten. Does it appear that the mean work week has increased for women at the role="math" localid="1650381098713" 5%level?
