Answer 11

You will need to find an online calculator that you can access, do the problem on a TI-Something calculator, or crank out the regression line by hand.

For now, I will show you what the output is for this problem.

Answer 12

thanks

Answer 15

@2kende

If you have a set of linear regression problems to solve, you will need to find a way to do them. I don't know why the site is blocked. There are others. And, you can always crank out the problem by hand.

Answer 16

if u woulda showed me the hand way i woulda did it wit u

Answer 17

An attachment from the Mathematica program using it's Fit function
is attached..
