Most popular questions from this chapter

Who studies more? Researchers asked the students in a large first-year college class how many minutes they studied on a typical weeknight. The back-to-back stemplot displays the responses from random samples of 30 women and 30 men from the class, rounded to the nearest 10 minutes. Write a few sentences comparing the male and female distributions of study time.

Fuel efficiency Refer to Exercise 48. Describe the distribution.

Strong paper towels In commercials for Bounty paper towels, the manufacturer claims that they are the “quicker picker-upper,” but are they also the stronger picker-upper? Two of Mr. Tabor’s statistics students, Wesley and Maverick, decided to find out. They selected a random sample of 30 Bounty paper towels and a random sample of 30 generic paper towels and measured their strength when wet. To do this, they uniformly soaked each paper towel with 4 ounces of water, held two opposite edges of the paper towel, and counted how many quarters each paper towel could hold until ripping, alternating brands. The data are displayed in the relative frequency histograms. Compare the distributions

Part (a). Would it be appropriate to use frequency histograms instead of relative frequency histograms in this setting? Explain why or why not.

Part (b). Compare the distributions of number of quarters until breaking for the two paper towel brands

Quiz grades Refer to Exercise 87.

(a) Find the median of Joey’s first 14 quiz grades.

(b) Find the median of Joey’s quiz grades after his unexcused absence. Explain why the 0 quiz grade does not have much effect on the median.

Which major? About 3 million first-year students enroll in colleges and universities each year. What do they plan to study?
