Suppose that a 90% confidence interval for a population mean μ is constructed from a sample, resulting in the interval from 110 to 150. what was the value of the sample mean that was collected? what was the size of the margin of error?

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

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.
