Chapter 3: Q 15. (page 173)

Points and turnovers Here is a scatterplot showing the relationship between

the number of turnovers and the number of points scored for players in a recent NBA season.15 The correlation for these data is r=0.92 Interpret the correlation.

Short Answer

Expert verified

The number of turnovers and the number of points scored by players have a strong and favorable relationship.

Step by step solution

01

Given information

Correlation,r=0.92

02

Explanation

A positive linear correlation exists when r is positive.

A negative linear correlation exists when r is negative.

For weak correlation,

0<|r|<0.5

For moderate correlation,

0.5<|r|<0.8

For strong correlation,

0.8<|r|<1

Note that

There is a substantial and positive correlation between points and turnovers.

More turnovers? Refer to Exercise 15 Does the fact that r=0.92 suggest

that an increase in turnovers will cause NBA players to score more points? Explain your reasoning.

Here are the weights (in milligrams) of 58 diamonds from a nodule

carried up to the earth’s surface in surrounding rock. These data represent a population of diamonds formed in a single event deep in the earth.

Make a histogram to display the distribution of weight. Describe the distribution.

Sarah’s parents are concerned that she seems short for her age. Their doctor has kept the following record of Sarah’s height:

a. Make a scatterplot of these data using age as the explanatory variable. Describe what you see.

b. Using your calculator, find the equation of the least-squares regression line.

c. Calculate and interpret the residual for the point when Sarah was 48 months old.

d. Would you be confident using the equation from part (b) to predict Sarah’s height when she is 40 years old? Explain.

Olympic figure skating For many people, the women’s figure skating competition is the highlight of the Olympic Winter Games. Scores in the short program x and scores in the free skate y were recorded for each of the 24 skaters who competed in both rounds during the 2010 Winter Olympics in Vancouver, Canada.28 Here is a scatterplot with least-squares regression line y^=−16.2+2.07x. For this model, s = 10.2 and r2 = 0.736.

It’s still early We expect that a baseball player who has a high batting average in the first month of the season will also have a high batting average for the rest of the season. Using 66 Major League Baseball players from a recent season,33 a least-squares regression line was calculated to predict rest-of-season batting average y from first-month batting average x. Note: A player’s batting average is the proportion of times at-bat that he gets a hit. A batting average over 0.300 is considered very good in Major League Baseball.

a. State the equation of the least-squares regression line if each player had the same batting average the rest of the season as he did in the first month of the season.

b. The actual equation of the least-squares regression line is y^=0.245+0.109x

Predict the rest-of-season batting average for a player who had a 0.200 batting average the first month of the season and for a player who had a 0.400 batting average the first month of the season.

c. Explain how your answers to part (b) illustrate regression to the mean.
