Data regarding the maintenance hours and costs for the last year and the results of the regression analysis are as follows: Jan. Har Apr. Maintenance Machine Month Cout Hours $ 5,040 540 Feb. 3.641 400 4,450 3,344 480 May 5,232 610 June 3,650 430 July 3,518 420 Aug. 5,350 710 Sept. 5,110 570 Oct. 4,862 580 3,926 470 3,870 400 $ 51,993 6,090 Average $4,332.75 507.50 Nov. Dec. Average cost per hour ($51,993/6,090) = $9.54 (rounded to the nearest cent) r=0.87671 2076862 The percent of the total variance that can be explained by the regression equation is: Multiple Choice 46.752% O 76.724% O O 76.862% O 76.903% O 58131%
