So, the best point estimate for the population's standard deviation is
Step 1 :Given that the sample variance is 6.6, we can find the standard deviation by taking the square root of the variance.
Step 2 :So, the standard deviation is
Step 3 :Using a calculator, we find that
Step 4 :Rounding to one decimal place, we get 2.6
Step 5 :So, the best point estimate for the population's standard deviation is
