91Ó°ÊÓ

More putting success Refer to your graph from Exercise 4 Describe the relationship between distance from hole and percent of putts made for the sample of professional golfers.

Short Answer

Expert verified

Negative, strong, curved association with no outliers.

Step by step solution

01

Given information

For scatterplot:

Horizontal axis: Distance (ft .)

Vertical axis: Percent made.

02

Explanation

Strength: The dots on the scatterplot are fairly close together in the pattern, and there are no significant deviations from this overall pattern. As a result, strength will be abundant.

Form: There looks to be a bit of curvature in the scatterplot. As a result, the shape will be slightly bent.

Direction: No points in the other scatterplot points significantly vary from the general pattern in the scatterplot. As a result, there are no outliers.

Olympic athletes The scatterplot shows the relationship between height (in

inches) and weight (in pounds) for the members of the United States 2016 Olympic Track and Field team.10 Describe the relationship between height and weight for these athletes.

Stats teachers’ cars A random sample of AP® Statistics teachers were asked to

report the age (in years) and mileage of their primary vehicles. Here are a scatterplot, a residual plot, and other computer output:

a. Is a linear model appropriate for these data? Explain how you know this.

b. What’s the correlation between car age and mileage? Interpret this value in context.

c. Give the equation of the least-squares regression line for these data. Identify any variables you use.

d. One teacher reported that her 6-year-old car had 65,000 miles on it. Find and interpret its residual.

e. Interpret the values of s and r2.

Heavy backpacks Ninth-grade students at the Webb Schools go on a

backpacking trip each fall. Students are divided into hiking groups of size 8 by selecting names from a hat. Before leaving, students and their backpacks are weighed. The data here are from one hiking group. Make a scatterplot by hand that shows how to backpack weight relates to body weight.

Crickets keep chirping In Exercise 44, we summarized the relationship between x = temperature in degrees Fahrenheit and y = chirps per minute for the striped ground cricket, with the regression line y^=–0.31+0.212x. For this model, technology gives s = 0.97 and r2 = 0.697.

a. Interpret the value of s.

b. Interpret the value of r2.

Will I bomb the final? We expect that students who do well on the midterm exam in a course will usually also do well on the final exam. Gary Smith of Pomona College looked at the exam scores of all 346 students who took his statistics class over a 10-year period. Assume that both the midterm and final exams were scored out of 100 points.

a. State the equation of the least-squares regression line if each student scored the same on the midterm and the final.

b. The actual least-squares line for predicting final exam score y from midterm-exam score x was y^=46.6+0.41x. Predict the score of a student who scored

50 on the midterm and a student who scored 100 on the midterm.

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