Question: The data in the following MINITAB output refer to an automobile’s stopping distance (in feet) at different speeds.

  1. What's the equation of the regression line you'd use to predict stopping distance based on speed? (4 points)
  2. Interpret the slope of the regression line. (4 points)
  3. Find a \(95 \%\) confidence interval for the slope of the regression line. (4 points)
  4. Test the hypothesis \(H_{0}: \beta_{1}=0\) and \(H_{a}: \beta_{1} \neq 0 .\) (7 points)
  5. 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)
