Question

eBook The exercise involving data in this and subsequent sections were designed to be solved using Excel. Consider the following estimated regression equation, based on 10 observations 29.1270 + 59061 49802 The values of SST and SSR are 6724.125 and 6216.375, respectively. a. Find SSE (to 2 decimals). 507.75 b. Compute R2 (to 3 decimals). 924 c. Compute R (to 3 decimals) .887 d. How good is the fit provided by the estimated regression egdation? The estimated regression equation provided an excellent fit

Explanation / Answer

here as independent variable k=2

and sample size n=10

therefore adjusted R2a =

=

( please try 0.903 if above comes wrong due to rounding)

1-(n-1)*SSE/(SST(n-k-1)) = 0.902
