Question

suppose that regression is run on 30 months of data. the dependent variable is overhead, and the independent variable is machine hours. the coeficient of determination is 0.78. which of the following is true

A. machine hours and overhead are negatively correlated

B. the coefficient of correlation is approximatelt 60%

C machine hours account for about 60.8% percent of the variation in overhead

D. factors other than machine hours account for 22 percent of the variation in overhead

E. none of the above

Explanation / Answer

In the given question the coefficient of determination was given as 0.78. it means r= 0.78 then r^2= 0.6084 or 60.84%.

It determines the relationship between changes in the factors.

So it explains though the option C. Machine hours Account for about 60.8% of the variable overhead.
