Question

If the mean of five observations is 24
and when a constant k is added to
each observation the AM becomes 27.
The value of k is:
1-3
2) 3
3) 4
4) 5​

Answer 1

Answer:

Step-by-step explanation:

K=3

Answer 2

Answer:

Step-by-step explanation:

sum of five / 5 = 24

sum of observations = 24*5 = 120

sum of observations + k +k ... 5 times k / 5 = 27

sum of observation + 5k = 27*5

120 + 5k = 135

5k = 15

k= 5
