Answer:
7.6811
Step-by-step explanation:
Given that is a sample of size 5, with readings as
14, 23, 31, 29, 33
Sum = 130: Hence mean = 130/5 =26
Let us find for each entry x the value x-26
X 14 23 31 29 33
(x-26)^2 144 9 25 9 49
Hence variance = average of
Std dev =
Population std dev = Sample std dev/sq rt (n-1)
=
