Answer #1

Solution :

n = 6

. $\bar x$ = $\sum x / n$ = 166 / 6 = 27.7

X	X - $\bar x$	(X - $\bar x$ )²
15	15 - 27.7 = -12.7
18	18 - 27.7 = -9.7
20	20 - 27.7 = -7.7	59.29
30	30 - 27.7 = 2.3	5.29
37	37 - 27.7 = 9.3	86.49
46	46 - 27.7 = 18.3	334.89
	Sum	741.333333
	Sum / (n -1)	741.33333/5 = 148.266666
	$\sqrt$ Sum / (n -1)	12.1765
