The following is part of regression output produced by Excel ( for Y vs X1 and X2):

12.9 6.1 1.1 39.7 3.4 5.9 8.9 15 7.3

0.9 0.8 1.0 0.3 0.4 0.7 0.71 0.5 0.9

4.2 3.1 1.2 15.7 2.5 0.7 5.0 6.4 3.0

A) write out the estimated regression equation showing that depends on X1 and X2.

b)if. X1=0.58 and X2=7.0, what is the value predicted for y

c)write the number which is the standard error of the regressions

d) which of the above value is the value of coefficient of multiple determination

e) if asked to do a simpler analysis by using only one of the two variables X1 and X2, which variable would be used?
