A sample of 8 golf balls is randomly selected and the following weights are measured in grams. Give a point estimate for the population variance. Round your answer to three decimal places. 45.15,45.12,45.19,45.08,45.21,45.17 ,45.14,45.24

And the sample variance is given by:

And replacing we got:

And this one is the best estimator for the population variance

Step-by-step explanation:

For this case we have the following data:

45.15,45.12,45.19,45.08,45.21,45.17,45.14,45.24

The first step would be calculate the sample mean given by:

And replacing we got:

And the sample variance is given by:

And replacing we got:

And this one is the best estimator for the population variance
