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

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
