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.
State the decision rule for .05 significance level. (Negative amounts should be indicated by a minus sign. Round your answers to 3 decimal places.)
Compute the value of the test statistic. (Round your answers to 2 decimal places. Negative amounts should be indicated by a minus sign.)
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.
Explanation / Answer
a) = 9.487 + 0.362 X1 + (-0.362) X2 +0.177 X3 +0.764 X4 +(-0.305) X5.
b)Sample n =61+1 =62
Independent variables k =5
c-1) Reject H0 if F >2.38
c-2) Computed value of F is 14.39
c-3)Reject Ho.
Not all of the regression coefficients are zero
d-1)
Reject H0 if t>2.003 or t<-2.003
d-2)
e) X3 and X5.
T-value X1 4.16 X2 -2.51 X3 -1.84 X4 3.94 X5 -1.86
