A machine is set to fill bottles with mL. Five bottles are pulled off the line and measured:
Treat these five bottles as the whole population of interest.
What is the population variance of the fill volumes?
Once you get it right, the reasoning behind the answer shows up here.
Select all that apply.
Visualize signed deviations, squaring, and the step-by-step calculation of variance.
Step 1: Calculate the Population Mean (μ)
Sum up all values and divide by N.
μ = () / 0 = 0 / 0 = 0
