The predict() function lets us apply the model to generate point and interval predictions. What is the interval estimate for a person (ok, frat boy) who has consumed 3, 4, or 5 beers?.

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
