Question
The manager of a used-car dealership is very interested in the resale price of used cars. The manager feels that the age of the car is important in determining the resale value. He collects data on the age and resale value of 15 cars and runs a regression analysis with the value of the car (in thousands of dollars) as the dependent variable and the age of the car (in years) as the independent variable. Unfortunately, the printout had lost some of the results, identified by"A" through"F". The partial results left are displayed below SUMMARY OUTPUT sion Statistics Multiple R R Square Adjusted R Square Standard Error 0.442 0.133 ations 15.000 ANOV TS 44.3973.154 F Significance F 44.397 0.09914 Residual Total 13 14 14.076 227.389 Coefficients Standard Error Sta P-vale 5.988 0.000 3,835 0.640 Age Compute the value of "D." o A 9.35 B. 3.06 C. 9.82 D. 22.96Explanation / Answer
as we know that t stat =coefficient/std error
therefore value of D =tstat for intercept*std error for intercept =5.988*3.835=22.96
therefore option D is correct
