What is the best point estimate for the population's standard deviation if the sample variance is 6.6 ? Round your answer to one decimal place, if necessary. Answer How to enter your answer (opens in new window) 5 Points Tables Kevboard Shor

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 \( \sqrt{6.6} \)

Step 3 ：Using a calculator, we find that \( \sqrt{6.6} \) is approximately 2.569046515733026

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 \(\boxed{2.6}\)
