Consider a sample of push pins. Their weights are measured and found to have a variance of 2.81. Give a point estimate for the population variance in weights of push pins. Round your answer to two decimal places, if necessary.

The best point estimate for population variance is 2.81

Step-by-step explanation:

We are given the following in the question:

We have a sample of pushpins.

The sample variance of weights of pushpins =

We have to estimate the population variance.

Point estimate foe population variance is the sample variance itself.

Thus, we can write:

Thus, the best point estimate for population variance of weights of pushpins is 2.81

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.

i believe the correct answer is b.
