There seems to be a relation between salaries (Y) obtained after graduation and tuition fees (X) paid to business school -- thus higher the tuition fees paid, higher the salaries offered by employers. Following data was obtained from 20 colleges (both X and Y were measured in $1000s

Xi = 680Yi = 2040(Xi-Xbar)(Yi-Ybar) = 1716

(Xi-xbar)²= 858(Yi-Ybar)²= 3980(Yhat-Ybar)²= 2937

Estimate the regression line Y = a + b Y. Calculate and interpret R², ANOVA, F, and t-values
