At the Thanksgiving break, I measured the correlation between the pre-class quiz grade and the average grade in the class for all 33 students in my stats classes. Below is the output from those results.

Correlation

Pearson correlation of PreClass and Grade = 0.705630

P-Value = <>

Regression Equation Grade = 0.24333 + 0.006369 PreClass

(a) What is the slope of the regression equation line?

(b) What does the slope of the line represent in this context?

(c) What is the y-intercept of the regression equation line?

(d) What does the y-intercept of the line represent in this context?
