Question
A regression model is built for a data set whose x -values are {5, 6.6, 7.5, 8.1, 9.3, 10.2, 11.4, 12.6, 13.9, 15}. Then confidence
A regression model is built for a data set whose x-values are {5, 6.6, 7.5, 8.1, 9.3, 10.2, 11.4, 12.6, 13.9, 15}.
Then confidence intervals for y are constructed at the four x-values 4.6, 5.2, 9.9, and 14.8.
Which confidence interval is going to be the narrowest?(5 points)
Which confidence interval was better off not being constructed at all, if any?(5 points)
