Question

Tecscin Company manufactures motorcycles. The company's management accountant wants to calculate the fixed and variable costs associated with utility cost incurred by the factory. Data for the past five months were collected as follows:

​

​	Utility	Machine
Month	cost	hours
March	$4,000	300
April	3,300	240
May	4,100	310
June	3,200	256
July	3,050	278

​

Using a regression program, the value of the intercept (rounded to the nearest whole number) is calculated as:

	a.	$1,289.
	b.	$3,256.
	c.	$2,113.
	d.	$1,900.

Answer 1

our needed calculation table be:-

cost(y)	hours(x)	x^2	y^2	xy
4000	300	90000	16000000	1200000
3300	240	57600	10890000	792000
4100	310	96100	16810000	1271000
3200	256	65536	10240000	819200
3050	278	77284	9302500	847900
sum=17650	sum=1384	sum=386520	sum=63242500	sum=4930100

so, we can calculate:-

so the intercept = $-69

***ANY OF THE OPTION IS NOT MATCHING..PLEASE CHECK THE OPTIONS AND THE GIVEN DATA ALSO...THE ANSWER WILL BE $-69
