The accompanying data table shows the engine â€‹size, x, in cubic

liters and rated miles per gallonâ€‹ (MPG), y, for a selection of

sedans. a. Using alpha Î± equals=â€‹0.05, test for the significance of

the regression slope. b. Construct aâ€‹ 95% confidence interval for

the population slope. c. What conclusions about engine size and MPG

can be drawn from theseâ€‹ results?
