A survey of the mean number of cents off that coupons give was conducted by randomly surveying one coupon per page from the coupon sections of a recent San Jose Mercury News. The following data were collected: 20; 65: 550 ; 65; 30; 55%; 40%; 40; 30%; 55¢; $1.50; 40%; 65; 40%. Assume the underlying distribution is approximately normal. If many random samples were taken of size 14, what percent of the 95% confidence intervals constructed should contain the population mean worth of coupons?

A population consists of the following five values: 0, 0, 6, 8, and 10.a. List all samples of size 3, and compute the mean of each sample. (Round your mean value to 2 decimal places.) b. Compute the mean of the distribution of sample means and the population mean. Compare the two values. (Round your answers to 1 decimal place.)
As a sample gets smaller and smaller, the sample mean tends to get closer and closer to the population. mean A. TrueB. FalseC. None of the above
In this problem, assume that the distribution of differences is approximately normal. Note: For degrees of freedom d.f. not in the Student's t table, use the closest d.f. that is smaller. In some situations, this choice of d.f. may increase the P-value by a small amount and therefore produce a slightly more "conservative" answer. In the following data pairs, A represents the cost of living index for utilities and B represents the cost of living index for transportation. The data are paired by metropolitan areas in the United States. A random sample of 46 metropolitan areas gave the following information.

In the following data pairs, A represents the cost of living index for utilities and B represents the cost of living index for transportation. The data are paired by metropolitan areas in the United States. A random sample of 46 metropolitan areas gave the following information. Do the data indicate that the U.S. population mean cost of living index for utilities is less than that for transportation in these areas? Use α = 0.05. (Let d = A − B.) (a) What is the level of significance? (b)What is the value of the sample test statistic? (Round your answer to three decimal places.)
