The following is the solution of number 12, and this one says to construct a 90 % confidence interval for the data in exercise 11, not exercise 11, exercise 12, from section 10 .2.

And this one's about a curb weight x in hundreds of pounds and the corresponding braking distance, y, and feet, for 50 mile per hour, i guess, cars on dry pavement.
00:23
So i'm going to use a ti84 here.
00:25
If you go to stat and then edit, here you can see the curb weight in hundreds of pounds.
00:30
So 25 represents 2 ,500 pounds, 27 .5, 32 .5, 35, and 45.
00:36
And then here we have breaking distance, and these are in feet, so 105 feet, 125 feet, 140, 140, and 150.
00:45
So then if we go to stat and then arrow over to test, and it's the second to last one where it says lin -reg t -int, go in there, x list should be l1, y list should be l2, frequencies one...
