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%; 55%; 65%; 30%; 55%; 40%; 40%; 30%; 55¢ ; $1.50; 40%; 65%; 40%. Assume the underlying distribution is approximately normal. Construct a 95% confidence interval for the population mean worth of coupons. a. State the confidence interval. (Round your answers to two decimal places.) b. Calculate the error bound. (Round your answer to two decimal places.)

A national publication showed the following distribution of favorite class subjects for high school students. Class Subject Math English Social Studies Physical Education Music Other Percentage 5% 14% 28% 26% 20% 7% Pasquale, a student from a high school of 1,200 students, wants to see whether the distribution at his school matches that of the publication. He stands at the school entrance in the morning and asks the first 40 students he sees what their favorite class is. Pasquale records the following table of observed values.

The histograms show the cost of living, in dollars, for 32 U.S. cities. The histogram on the left shows the cost of living for the 32 cities using bins $10 wide, and the histogram on the right displays the same data using bins that are $6 wide. Compare the distributions (shape, center, spread, unusual features). Choose the best answer below: a. The distribution in the left histogram of the cost of living in the 32 U.S. cities is unimodal and skewed to the right. The distribution is centered around $100, and spread out, with values ranging from $80 to $140. The distribution in the right histogram appears bimodal, with many cities costing just under $104 and another smaller cluster around $119. b.
