Chapter 3: Q.16 (page 161)

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.

Short Answer

Expert verified

The correlations between these pairs of variables from highest to lowest:

Women age: 4-18.

Father-Son.

Husband-Wive.

Step by step solution

01

Given Information

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 4 and their heights at age 18.

02

Explanation 

To rank the correlations between these pairs of variables from highest to lowest:

Because the data pertains to the same individuals, the strongest link should be between women aged 4and 18.

Because fathers and sons are linked, there will be a substantial correlation between them, but not as strong as a correlation between variables relating to the same individual.

Because husbands and wives are relatives, they should have the least in common in terms of height.

The risks of obesity A study observes a large group of people over a 10-year period. The goal is to see if overweight and obese people are more likely to die during the study than people who weigh less. Such studies can be misleading because obese people are more likely to be inactive

and poor.

(a) What are the explanatory and response variables in the study?

(b) If the study finds a strong association between these variables, can we conclude that increased

weight causes a greater risk of dying? Why or why not?

Oil and residuals Refer to Exercise 59. The following figure shows a residual plot for the least-squares regression line. Discuss what the residual plot tells

A government report looked at the amount borrowed for college by students who graduated in 2000and had taken out student loans.12 The mean amount was x=\(17,776and the standard deviation was sx=\)12,034. The median was\(15,532and the quartiles were Q1=\)9900and Q3=\(22,500.

(a) Compare the mean and the median. Also compare the distances of Q1 and Q3 from the median. Explain why both comparisons suggest that the distribution is right-skewed.

(b) The right-skew pulls the standard deviation up. So a Normal distribution with the same mean and standard deviation would have a third quartile larger than the actual Q3.Find the third quartile of the Normal distribution with渭=\)17,776and 蟽=\(12,034and compare it withQ3=\)22,500.
