Here, once again, is the stem plot of travel times to work for 20randomly selected New Yorkers. Earlier, we found that the median was 22.5

Use your calculator to find the mean travel time. Was your answer to Question 1 correct?

Earthquake intensities are measured using a device called a seismograph, which is designed to be most sensitive to earthquakes with intensities between 4.0 and 9.0 the Richter scale. Measurements of nine earthquakes gave the following readings:

where L indicates that the earthquake had an intensity below 4.0 and an H indicates that the earthquake had an intensity above 9.0. The median earthquake intensity of the sample is (a) 5.75. (c) 6.47. (e) Cannot be determined. (b) 6.00. (d) 8.70.

Do women study more than men? We asked the students in a large first-year college class how many minutes they studied on a typical weeknight. Here are

the responses of random samples of 30 women and 30 men from the class:

(a) Examine the data. Why are you not surprised that most responses are multiples of 10 minutes? Are there any responses you consider suspicious?

(b) Make a back-to-back stem plot to compare the two samples. Does it appear that women study more than men (or at least claim that they do)? Justify your answer.

Snowmobiles in the park Yellowstone National Park surveyed a random sample of 1526 winter visitors to the park. They asked each person whether they owned, rented, or had never used a snowmobile. Respondents were also asked whether they belonged to an environmental organization (like the Sierra Club). The two-way table summarizes the survey responses.

Do these data provide convincing evidence of an association between environmental club membership and snowmobile use for the population of visitors to Yellowstone National Park? Follow the four-step process.
