the regression analysis is given above in excel figure.
regression equaltion: y = -0.0985x + 9795.49
y = freshman enrolled
x = tuition fees
If the fees is increased by 9000
new fees = 57700 + 9000 = 66700
Hence x = 66700
Freshman enrollment = -0.0985*66700 + 9795.49 = 3225.54 = 3226
c) R = 0.9096
R squared = 0.8273
Standard error S = 389.736
The R and R squared tells us that the 82% of the data is proportional of explains the obtained result. Which is a good number. But the S of 389 says that there is potential for a huge error in this result. Hence, more observations would help us reduce the error in the analysis.
