Question

Find s. Consider the set of differences between two dependent​ sets: 84,​ 85, 83,​ 63, 61,​ 100, 98. Round to the nearest tenth.

Answer 1

Answer:

s  is $s =15.3$

Step-by-step explanation:

From the question we are told that

    The data is  

Generally the mean is evaluated as

           $\= x = \frac{84+ 85+ 83+​ 63+ 61+​100+ 98}{7}$

           $\= x = 82$

The standard deviation is mathematically represented as

    $s = \frac{\sum (x- \= x)^2}{n-1}$

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

 $s =15.3$
