This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

Suppose we have the following information from a simple regression:
b0 = 117.4
b1 = -14.39
sb0 = 44.17
sb1 = 3.20
n = 300
x = 4.3
SST = 17,045
SSE = 12,053

a. What is the coefficient of determination?
b. What is the correlation coefficient?
c. What is the sample mean of y?
d. What is the value of the sample test statistic for the hypothesis test H0: B1 = 0 vs. B2 does not equal 0 with alpha = 0.05?
