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?
The coefficient of determination is (12053/17045)^2 = 0.50003. So the answer is ...
This solution is comprised of a detailed explanation of a regression analysis question. The solution also depicts that how answers are derived for these four sub parts.
