Eleven students took part in an evaluation program designed to measure teacher effectiveness and determine what factors are important. The response measure was a quantitative evaluation of the teacher done by the student. The regressor variable was the student's score on a standardized test.

a) Fit an appropriate linear model, analyze the fit of your results, discuss why you selected the model you did and what you can say about the prediction of the standardized test towards teacher evaluations.

b) Using =0.05, test whether the slope equals zero and also whether the population correlation coefficient equals zero.
