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

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.
