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 :

the solution is 12x-6y

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
