Question

13, 5, 4, 9, 7, 14, 4 The deviations are _____.

A. "5, -3, -4, 0, 1, 6, 4"
B."5, -3, -4, 1, -1, 6, -4"
C."6, -3, -4, 1, 2, 6, -4"
D."-5, 3, 4, -1, 1, 6, 4 "

Answer 1

B."5, -3, -4, 1, -1, 6, -4"

Explanation:

We are given that

13,5,4,9,7,14,4

We have to find the deviation.

Mean=
`(sum\;of\;data)/(total\;number\;of\;data)`

Using the formula

`Mean,\mu=(13+5+4+9+7+14+4)/(7)`

`Mean,\mu=(56)/(7)=8`

Deviation=
`x_i-\mu`

`x_i-\mu`

13 5

5 -3

4 - 4

9 1

7 -1

14 6

4 - 4

Hence, option B is correct.
