If population function x has mean M(x)=2 and M(x²)=8, find its standard deviation
1 answer:
The standard deviation of the population function is 2
<h3>How to determine the standard deviation?</h3>The given parameters are:
M(x) = 2
M(x²)=8
The standard deviation is calculated using:
Substitute known values
Evaluate the expression
Hence, the standard deviation of the population function is 2
