So for the first part of this question, you have to use a linear regression model.
00:07
The equation for this would be final equals a plus b times your test score.
00:16
In order to find estimates for the a and b coefficients, most of the times you're just going to be using a statistical calculator.
00:27
You can do this manually, but i think for the sake of this question, it's just asking you to use some type of calculator software to provide a best estimate for a and b.
00:41
So using those, you get an estimate for a as 53 .53, and b, once you find these estimates, you can kind of create your equation here.
00:57
Final is going to be 52, and these kind of coefficients were found just by inputting all the data and coming up onto a statistical calculator, which allows you to get estimates for these two coefficients.
01:20
So for part b, it asks to find standard error.
01:30
So for part b, you calculate the average distance between the observed values and the predicted values from the regression model...
