FIGURE D16.Id The regression equation ia Y - - 169 + 12.2

This regression is made using Minitab software.

Question:
i. Use the t test and a = 0.05 to test the hypothesis H0: H1 = 0 and H0: H2 = 0.
ii. Determine the SSE value.

RELATIONSHIPS BETWEEN SST, SSR, AND SSE
SST = SSR + SSE
iii. Determine the value of R2 and explain its meaning. R2 = SSR/SST
