Question:

Refer to the data of speed x and stopping distance y given in Table 1.
The MINITAB commands for fitting a straight line regression to y€² = ˆšy and x are

(a) Obtain the computer output and identify the equation of the fitted line and the value of r2 (see Example 1).
(b) Give a 95% confidence interval for the slope.
(c) Obtain a 95% confidence interval for the expected y' value at x = 45.
