Discuss any afferences you observe between the a and previous cal years The mean sales amount has from the previous to most recent fiscal year. The amount of change is compared to the standard deviation in strong likelihood that -- the fiscal year. Therefore, there is a

Answer 1

		Sales Amount(X)	X-MEAN	(X-MEAN)^2
1	Joseph	$148,000	-$167,643	$28,104,175,449
2	Jennifer	$231,000	-$84,643	$7,164,437,449
3	Philip	$548,000	$232,357	$53,989,775,449
4	Standley	$329,000	$13,357	$178,409,449
5	Luke	$296,000	-$19,643	$385,847,449

7	Margarer	$367,000	$51,357	$2,637,541,449
8	Wei	$464,000	$148,357	$22,009,799,449
9	Samantha	$409,000	$93,357	$8,715,529,449
10	Erin	$297,000	-$18,643	$347,561,449
11	Dominic	$322,000	$6,357	$40,411,449
12	Charlie	$189,000	-$126,643	$16,038,449,449
13	Amol	$212,000	-$103,643	$10,741,871,449
14	Lenisa	$414,000	$98,357	$9,674,099,449
	Total	$4,419,000		$175,069,214,286
		$315,643
(a)	MEAN = 4,419,000/14 = 315,643
	Variance = (Sum of (X-Mean)^2)/N
	Variance	$12,504,943,878
	Standard deviation	$111,826	Variance^(1/2) ie. (12,504,943,878)^(1/2)
(b)	The mean sales has INCREASED from the previous to most recent fiscal year.
