Term	Number of Sections Offered		Total Cost
Fall, lastyear		4	$	13,000
Winter,last year		3	$	7,500
Summer,last year		7	$	13,500
Fall, thisyear		5	$	10,000
Winter,this year		2	$	6,500

Professor Morton knows that thereare some variable costs, such as amounts paid to graduateassistants, associated with the course. He would like to have thevariable and fixed costs separated for planning purposes.

Required:
1.	Prepare a scattergraphplot. (Place total cost on the vertical axis and number ofsections offered on the horizontal axis.)

Instructions:
1.	On the graphbelow, use the point tool (Fall last year) to plot number ofsections offered on the horizontal axis and total cost on thevertical axis.
2.	Repeat the sameprocess for the plotter tools (winter last year to winter thisyear).
3.	To enter exactcoordinates, click on the point and enter the values of x andy.
4.	To remove apoint from the graph, click on the point and select deleteoption.

2(a).	Using the least-squares regression method, estimate the variablecost per section and the total fixed cost per term for Finance 101.(In the calculation, round your fixed cost and variablecost to nearest whole dollars.)

2(b).	Express these estimates in the linear equation form Y =a + bX.

3a.	Assume that because of the small number of sections offeredduring the Winter Term this year, Professor Morton will have tooffer nine sections of Finance 101 during the Fall Term. Computethe expected total cost for Finance 101. (Round your finalanswer to nearest whole dollar.)

3b.	Can you see any problem withusing the cost formula from (2) above to derive this total costfigure?

	Choose the BEST answer from thefollowing choices:

	Prediction is out of the relevantrange.
	Prediction is based on olddata.
	Prediction is not guaranteed tobecome actual.
	Coefficient estimates may have highvariance.
