Question: The data in the following MINITAB output refer to an automobile’s stopping distance (in feet) at different speeds.
- What's the equation of the regression line you'd use to predict stopping distance based on speed? (4 points)
- Interpret the slope of the regression line. (4 points)
- Find a \(95 \%\) confidence interval for the slope of the regression line. (4 points)
- Test the hypothesis \(H_{0}: \beta_{1}=0\) and \(H_{a}: \beta_{1} \neq 0 .\) (7 points)
- Suppose, instead of testing \(H_{0}: \beta_{1}=0\), you decided to test \(H_{0}: \beta_{1}=5\) against \(H_{a}: \beta_{1} \neq 5 .\) What \(P\) -value would be associated with this test? (7 points)
