Answer 1

Since the table for the data using excel as

	Xi	Yi	Xi*Yi
	4	2	8
	-1	6	-6
	8	0	0
	2	5	10
	1	2	2
	4	-1	-4
	3	-18	-54
Sum=	21	-4	-44
Mean(M)=	3	-0.57143

So,

6. S_X= Sum of X=21

7. S_y= Sum of Y =-4

8. S_XY= Sum of the product of X and Y =-44

9.m is the slope of the data is calculated as by the table shown below as

X-м, Y- M (X- MxJ2 2.5714 6.5714 0.5714 5.5714 2.5714 -0.4286 -17.4286 2.5714 -26.2857 2.8571 -5.5714 -5.1429 -0.4286 16 25 Ss: 48 SP: -32

m= SP/SS_X = -32/48 = -0.66667
