Problem 11

An Unhealthy Commute The following data represent commute times (in minutes) and a score on a well-being survey.

Use the results from Problem 17 in Section 4.2 to answer the following questions:

(a) Treating commute time as the explanatory variable, x, determine the estimates of 0 and 1.

(b) Compute the standard error of the estimate, Se.

(c) Determine Sb1.

(d) A normal probability plot of the residuals indicates it is reasonable to conclude the residuals are normally distributed. Test whether a linear relation exists between commute time and well-being index composite score at the a = 0.05 level of significance.

(e) Construct a 95% confidence interval about the slope of the true least-squares regression line.

(e) Construct a 95% confidence interval about the slope of the true least-squares regression line. Summary In this chapter, we introduced probability models for random variables. A random variable represents the numerical measurement of the outcome from a probability experiment.
