  1. Suppose we have the following data on variable X (independent) and variable Y (dependent):
X Y
2 70
0 70
4 130

a.) By hand, determine the simple regression equation relating Y and X.

b.) Calculate the R-Square measure and interpret the result.

c.) Calculate the adjusted R-Square.

d.) Test to see whether X and Y are significantly related using a test on the population correlation. Test this at the 0.05 level.

e.) Test to see whether X and Y are significantly related using a t-test on the slope of X. Test this at the 0.05 level.

f.) Test to see whether X and Y are significantly related using an F-Test on the slope of X. Test this at the 0.05 level.
