Question

The following regression output was obtained from a study of architectural firms. The dependent variable is the total amount of fees in millions of dollars.

Write out the regression equation. (Round your answers to 3 decimal places. Negative amounts should be indicated by a minus sign.)

State the decision rule for .05 significance level: H0: 1 = 2 = 3 =4 =5 =0; H1: Not all 's are 0. (Round your answer to 2 decimal places.)

Can we conclude that the set of regression coefficients could be different from 0? Use the .05 significance level.

H0. of the regression coefficients are zero.

Explanation / Answer

a) Yhat=10.487+0.402 X1-0.402 X2+0.217 X3+0.804 X4-0.345 X5

b) DF(Regresion)=k-1=5, k=6

DF(Total)=n-1=52, n=53

c.1. The critical F for df(6,53), alpha=0.05 is 2.28.

Reject H0, if F>2.28

c2. 15.39

c3. Test statistic falls in critical region. Reject null hypothesis. Conclude that set of regression coefficients could bedifferent from 0.
