A sample of 8 buttons is randomly selected and the following diameters are measured in inches. Give a point estimate for the population standard deviation. Round your answer to three decimal places. 1.83,1.85,1.79,1.73,1.69,1.74,1.76, 1.70

Now we can estimate the population variance with the sample variance given by:

And replacing we got:

And the estimator for the population deviation is given by :

Step-by-step explanation:

For this case we have the following data given:

1.83,1.85,1.79,1.73,1.69,1.74,1.76,1.70

First we need to calculate the mean with the following formula:

And replacing we got:

Now we can estimate the population variance with the sample variance given by:

And replacing we got:

And the estimator for the population deviation is given by :

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will
