Consider the pairs of measurements in the table below. Complete parts a through f. x - 2 0 y 0 2 (ION NO) 10 11 :1. Construct a scattergram for these data. Choose the correct scattergram below. 5:3 A. 11y @ Q x @ x @ Q @ -3 11 I). Find the least squares line, and plot it on your scattergram. The least squares line is = 1.5 + 0.94x. (Round to three decimal places as needed.) b. Find the least squares line, and plot it on your scattergram. The least squares line is 9 = 1.5 + 0.946'x. (Round to three decimal places as needed.) Plot the least squares line on the scattergram. Choose the correct graph below. a} A. (KB. {:3 c. @96 9. Find a 95% prediction interval for a new value of y when x = 7. Plot the upper and lower bounds of the prediction interval on your scattergram. The 95% prediction interval is (DD). (Round to three decimal places as needed.) f. Compare the widths of the intervals you constructed in parts d and e. Which is wider and why? The (1) is the wider of the two intervals because the error in this interval is (2) (1) O confidence interval for the mean value of y (2) O twice the error of the first interval O prediction interval for y O random error the error of estimation plus random error
