Chapter 3: Q.13 (page 160)

Merlins breeding The percent of an animal species in the wild that survives to breed again is often lower following a successful breeding season. A study of merlins (small falcons) in northern Sweden observed the number of breeding pairs in an isolated area and the percent of males (banded for identification) that returned the next breeding season. Here are data for nine years:

Investigate the relationship between breeding pairs and percent return. Follow the four-step process.

Short Answer

Expert verified

Direction: Negative

Form: Curved

Strength: Moderate relationship.

Step by step solution

01

Given Information 

Data for nine years:

02

Explanation

The horizontal axis represents breeding pairs, while the vertical axis represents percent return.

03

Explanation

Direction: The direction is negative, Because the scatterplot slopes downhill.

Form: The form is curved, Because the scatterplot has curvature.

Strength: Moderate, since the points are not too far apart but not too close together.

We expect a car's highway gas mileage to be related to its city gas mileage. Data for all 1198vehicles in the government's 2008Fuel Economy Guide give the regression line predicted highway mpg=4.62+1.109(city mpg).

(a) What’s the slope of this line? Interpret this value in context.

(b) What’s the intercept? Explain why the value of the intercept is not statistically meaningful.

(c) Find the predicted highway mileage for a car that gets 16miles per gallon in the city. Do the same for a car with a city mileage of 28mpg.

Measurements on young children in Mumbai, India, found this least-squares line for predicting height yfrom the arm span x y⏜=6.4+0.93xMeasurements are in centimeters (cm).

One child in the Mumbai study had a height of 59cmand an arm span60cmThis child’s residual is

(a)−3.2cm.(c)−1.3cm.(e)62.2cm.(b)−2.2cm.(d)3.2cm.

Rank the correlations Consider each of the following relationships: the heights of fathers and the heights of their adult sons, the heights of husbands and the heights of their wives, and the heights of women at age 4and their heights at age 18. Rank the correlations between these pairs of variables from highest to lowest. Explain your reasoning.
