Easy reading? Refer to Exercise 46. Describe the shape of the distribution.

Short Answer

Expert verified

Roughly symmetric

Single peak

No gaps

Step by step solution

01

Step 1. Given information

Here are data on the lengths of the first 25 words from Toni Morrison鈥檚 Song of Solomon:

02

 Step 2. make a number line for each piece of data Put a dot on the number line above the corresponding number.

03

 Step 3. The shape of the distribution.  

The peak in the dotplot is roughly in the middle of the graph, indicating that the distribution is roughly symmetric.

We notice that the distribution has a single peak at 7, and there appear to be no (large) gaps in the dotplot.

Roughly symmetric

Single peak

No gaps

Women and children first? Here鈥檚 another table that summarizes data on survival status by gender and class of travel on the Titanic:

(a) Find the distributions of survival status for males and for females within each class of travel. Did women survive the disaster at higher rates than men? Explain.

(b) In an earlier example, we noted that survival status is associated with class of travel. First-class passengers had the highest survival rate, while third-class passengers had the lowest survival rate. Does this same relationship hold for both males and females in all three classes of travel? Explain.

Paying for championships Does paying high salaries lead to more victories in professional sports? The New York Yankees have long been known for having Major League Baseball鈥檚 highest team payroll. And over the years, the team has won many championships. This strategy didn鈥檛 pay off in 2008, when the Philadelphia Phillies won the World Series. Maybe the Yankees didn鈥檛 spend enough money that year. The figure shows histograms of the salary distributions for the two teams during the 2008 season. Why can鈥檛 you use these graphs to effectively compare the team payrolls?

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.

Facebook and age Refer to the preceding exercise.
