Answer :
The best point estimate for the population's standard deviation would be 39.1.
Point Estimate for a population standard deviation
In mathematics, we often use the sample standard deviation as a point estimate for the population standard deviation. Therefore, the best point estimate for the population's standard deviation would be 39.1.
When estimating a population's standard deviation, one approach is to use the sample standard deviation as a point estimate. Since the sample standard deviation is 39.1, it could be considered the best point estimate for the population's standard deviation.
However, it is essential to remember that this is only an estimate and may not precisely match the actual value of the population's standard deviation.
