Chapter 1: Q 47. (page 47)

U.S. women鈥檚 soccer鈥�2016 Earlier, we examined data on the number of goals scored by the 2016 U.S. women鈥檚 soccer team in 20 games played. The following dotplot displays the goal differential for those same games, computed as U.S. goals scored minus opponent goals scored.

Part (a). Explain what the dot above 3 represents.

Part (b). What does the graph tell us about how well the team did in 2016? Be specific.

Short Answer

Expert verified

Part (a) In one game, the 2016 US soccer team outscored the opponent by three goals.

Part (b) The 2016 US soccer team appears to have played very well, as they tied three games and won the rest.

Step by step solution

01

Part (a) Step 1. Given information.

2016 U.S. Women's Soccer Championship Previously, we looked at data on the number of goals scored by the 2016 US women's soccer team in 20 games.

02

Part (a) Step 2. The dot above 3 represents.   

The dots in the dotplot represent the number of goals scored in a game between the 2016 United States women's soccer team and an opponent.

The dot above 3 represents one game in which the 2016 US soccer team scored three goals more than the adversary

In one game, the 2016 US soccer team outscored the opponent by three goals.

03

Part (b) Step 1. The difference in the number of goals is represented by a dotplot.

The dots in the dotplot represent the number of goals scored in a game between the 2016 United States women's soccer team and an opponent.

We can see that there are three dots above zero, implying that the 2016 US women's soccer team scored the same number of goals as their opponent in three games, and thus tied three games.

All other dots in the dotplot are placed above a positive integer, implying that the 2016 U.S. women's soccer team scored more goals than their opponents in the other games and thus won all games except the three tied games.

The 2016 US soccer team appears to have played very well, as they tied three games and won the rest.

Shopping spree The stemplot displays data on the amount spent by 50 shoppers at a grocery store. Note that the values have been rounded to the nearest dollar.

Part (a) What was the smallest amount spent by any of the shoppers?

Part (b) Describe the distribution of amount spent by these 50 shoppers.

. Which of the following is the best reason for choosing a stemplot rather than a histogram to display the distribution of a quantitative variable?

a. Stemplots allow you to split stems; histograms don鈥檛.

b. Stemplots allow you to see the values of individual observations.

c. Stemplots are better for displaying very large sets of data.

d. Stemplots never require rounding of values.

e. Stemplots make it easier to determine the shape of a distribution.

Carbon dioxide emissions Burning fuels in power plants and motor vehicles emits carbon dioxide (CO2 ), which contributes to global warming. The table displays CO2 emissions per person from countries with populations of at least 20 million. 30

Part (a). Make a histogram of the data using intervals of width 2, starting at 0.

Part (b). Describe the shape of the distribution. Which countries appear to be outliers

Risks of playing soccer (1.1) A study in Sweden looked at former elite soccer players, people who had played soccer but not at the elite level, and people of the same age who did not play soccer. Here is a two-way table that classifies these individuals by whether or not they had arthritis of the hip or knee by their mid-fifties:

Part (a). What percent of the people in this study were elite soccer players? What percent of the people in this study developed arthritis?

Part (b). What percent of the elite soccer players developed arthritis? What percent of those who got arthritis were elite soccer players?

Part (c). Researchers suspected that the more serious soccer players were more likely to develop arthritis later in life. Do the data confirm this suspicion? Calculate appropriate percentages to support your answer.
