Consider the following pairs of measurements:
a. Construct a scattergram for these data.
b. What does the scattergram suggest about the relationship between x and y?
c. Find the least squares estimates of P,, and P, on the MINITAB printout below.
d. Plot the least squares line on your scattergram. Does the line appear to fit the data well? Explain. e. Interpret the y-intercept and slope of the least squares line. Over what range of x are these interpretations meaningful?
