Oil and residuals Exercise 53 on page 194 (Chapter 3) examined data on the depth of small defects in the Trans-Alaska Oil Pipeline. Researchers compared the results of measurements on 100 defects made in the field with measurements of the same defects made in the laboratory.6 The figure below shows a residual plot for the least-squares regression line based on these data. Explain why the conditions for performing inference about the slope b of the population regression line are not met.

ANSWER:Step 1 of 2
The figure shows a residual plot for the least-squares regression line based on comparison of the measurements on 100 defects made in the field with measurements of the same defects made in the laboratory. We have to explain why the conditions for performing inference about the slope
