Regression and Predictions. Exercises 13–28 use the same data sets as Exercises 13–28 in Section 10-1. In each case, find the regression equation, letting the first variable be the predictor (x) variable. Find the indicated predicted value by following the prediction proce- dure summarized in Figure 10-5 on page 507. | 14. Old Faithful Using the listed duration and interval after times, find the best predicted "in- terval after" time for an eruption with a duration of 253 seconds. How does it compare to an actual eruption with a duration of 253 seconds and an interval after time of 83 minutes? 242 255 227 251 262 207 140 Duration Interval After 91 81 91 102 94 91 92
