The average grade for the class decreases by about
Explanation of Solution
Given information:
The table at the right shows the relationship between the number of students in a mathematics class and the average grade for each class.
Describe the correlation? How accurate is the regression equation.
Calculation:
Consider the equation for line of regression.
It can be interpolated from the slope of regression line that the average grade for the class decreases by about
Hence, the average grade for the class decreases by about
