Chapter 1: Q 117. (page 78)

Who texts more? For their final project, a group of AP Statistics students wanted to compare the texting habits of males and females. They asked a random sample of

students from their school to record the number of text messages sent and received over a two-day period. Here are their data:

a. Make parallel boxplots of the data.

b. Use your calculator to compute numerical summaries for both samples.

c. Do these data suggest that males and females at the school differ in their texting

habits? Use the results from parts (a) and (b) to support your answer.

Short Answer

Expert verified

a.

b. For male: n=15,MaxX=214and for female: n=16,MaxX=379

c. Females are texting more frequently.

Simpson鈥檚 paradoxAccident victims are sometimes taken by helicopter from the accident scene to a hospital. Helicopters save time. Do they also save lives? The two-way table summarizes data from a sample of patients who were transported to the hospital by helicopter or by ambulance.

(a) What percent of patients died with each method of transport? Here are the same data broken down by severity of accident:

(b) Calculate the percent of patients who died with each method of transport for the serious accidents. Then calculate the percent of patients who died with each method of transport for the less serious accidents. What do you notice?

(c) See if you can explain how the result in part (a) is possible given the result in part (b).

Note: This is an example of Simpson鈥檚 paradox, which states that an association between two variables that holds for each value of a third variable can be changed or even reversed when the data for all values of the third variable are combined.

Value of a diploma Do students who graduate from high school earn more money than students who do not? To find out, we took a random sample of 371 U.S. residents aged 18 and older. The educational level and total personal income of each person were recorded. The data for the 57 non-graduates (No) and the 314 graduates (Yes) are displayed in the relative frequency histograms.

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 total personal income for the two groups.

Disc dogs Here is a list of the breeds of dogs that won the World Canine Disc Championships from 1975 through 2016. Make a relative frequency bar graph for these data. Describe what you see.

Who buys cars? A car dealer keeps records on car buyers for future marketing purposes. The table gives information on the last 4 buyers.

Part (a). Identify the individuals in this data set.

Part (b). What variables were measured? Classify each as categorical or quantitative.

You look at real estate ads for houses in Naples, Florida. There are many houses ranging from \(200,000 to \)500,000 in price. The few houses on the water, however, are priced up to $15 million. The distribution of house prices will be
