Answer:

s is
s =15.3

Explanation:

From the question we are told that

The data is

Generally the mean is evaluated as

$\= x = (84+ 85+ 83+ 63+ 61+100+ 98)/(7)$

$\= x = 82$

The standard deviation is mathematically represented as

$s = (\sum (x- \= x)^2)/(n-1)$

$s =\sqrt{ ( (84-82)^2+ (85-82)^2 +( 83-82 )^2 +(63-82) ^2 + ( 61-82)^2,+ (100-82)^2 + (98-82)^2)/(7-1)}$

s =15.3
