Question
A shoe store developed the following estimated regression equation relating sales to inventory investment and advertising expenditures.
i25+10z + 8
where
1= inventory investment ($L000s)
I2= advertising expenditures ($1000s)
y= sales ($1000s)
The data used to develop the model came from a survey of 10 stores; for those data, SST= 18,000 and SSR – 11,000.
a. Compute SSE, MSE, and MSR (to 2 decimals, if necessary).
SSE -
MSE -
MSR -
b. Use an F test and o = 0.05 level of
