I got 1.10 for number 1 and 3.46 for number 2. Hopefully that's right, but I have no idea how to do number 3.

Class Problem Estimate the coefficients for the model y = bo + bix, + er. Question 1 EX xy What do you calculate for b,? 3 3 3 21 9 Question 2 5 11 55 25 What do you calculate for bo? 2 3 6 4 6 12 72 36 Question 3 17 36 157 75 if I had an X of 10, what would you E-(x; - x) ( yi - y) nExy - [( x ) (Ly)] expect Y to be based b1 n Ex? - (Ex)2 on the results of your ET-1 (xi - x ) 2 regression? I bo = y - bix
