Answer 1

Ans:

minimum=6

maximum=97

Range=97-6=91

	xi	(xi-62.727)^2
1	49	188.438
2	6	3217.983
3	43	389.165
4	67	18.256
5	66	10.711
6	34	825.256
7	88	638.711
8	95	1041.529
9	97	1174.620
10	90	743.802
11	55	59.711
Total	690	8308.182
mean	62.72727

sample variance=8308.182/(11-1)=830.8

sample standard deviation=sqrt(830.818)=28.8
