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 22 colleges (both x and y were measured in $,000s):                                         

∑xi = 770                    ∑yi = 1496                  Coeff of correlation (rxy) = 0.6286

∑(xi − xbar)2 = 2541     ∑(yi − ybar)2 = 4116     ∑(yhat − ybar)2 = 3591

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