Answer:
4.
Step-by-step explanation:
First work out the mean:
Mean = (2 + 5 + 6 + 8 + 14) / 5
= 35/5 = 7.
Now subtract the mean form each of the values:
2 - 7 = -5
5 - 7 = -2
6 - 7 = -1
8 - 7 = 1
7 - 14 = -7.
The squares of these are 25, 4, 1, 1, 49
Their sum = 25 + 4 + 1 + 1 + 49 = 80
Now divide this by 5 = 16.
Standard deviation is ā16 = 4.
M(12,9)
N(12,-9)
