You are testing the null hypothesis that there is no linear relationship between two variables, X and Y. From your sample of n = 20, you determine that SSR = 60 and SSE = 40.
a. What is the value of FSTAT?
b. At the a = 0.05 level of significance, what is the critical value?
c. Based on your answers to (a) and (b), what statistical decision should you make?
d. Compute the correlation coefficient by first computing r 2 and assuming that b1 is negative.
e. At the 0.05 level of significance, is there a significant correlation between X and Y?
