Armer Company is accumulating data to use in preparing its
annual profit plan for the coming year. The cost behavior pattern
of the maintenance costs must be determined. The accounting staff
has suggested the use of linear regression to derive an equation
for maintenance hours and costs. Data regarding the maintenance
hours and costs for the last year and the results of the regression
analysis follow:
Month | Maintenance Cost | Machine Hours | ||||
Jan. | $ | 4,550 | 620 | |||
Feb. | 3,350 | 460 | ||||
Mar. | 3,950 | 540 | ||||
Apr. | 3,170 | 440 | ||||
May | 4,700 | 640 | ||||
June | 3,310 | 450 | ||||
July | 3,380 | 460 | ||||
Aug. | 4,820 | 680 | ||||
Sept. | 4,610 | 630 | ||||
Oct. | 4,400 | 610 | ||||
Nov. | 3,650 | 490 | ||||
Dec. | 3,510 | 480 | ||||
Sum | $ | 47,400 | 6,500 | |||
Average | $ | 3,950 | $ | 542 | ||
Average cost per hour | $ | 7.00 | ||||
a (intercept) | $ | 129.7693 | ||||
b (coefficient) | 7.0527 | |||||
Standard error of the estimate | 52.8466 | |||||
R-squared | 0.9935 | |||||
t-value for b | 39.130 | |||||
The percent of the total variance that can be explained by the
regression equation is
Answer = 99.35%
Explanation:
The coefficient of Determination or R-squared is the measure of the percent of the total variance that can be explained by the regression equation so r - squared is 0.9935 which gives are answer 99.35%
