The mean of a population being sampled is 64, and and the standard deviation is 6. if the sample size is 50, the standard error of the mean is . (round off your answer to the nearest hundredth.)

The standard error of the mean is 0.85.              

Step-by-step explanation:

Given : The mean of a population being sampled is 64, and and the standard deviation is 6.  If the sample size is 50.

To find : The standard error of the mean ?

Solution :

The mean of the population is

The standard deviation is

The sample size is n=50

Standard error of the mean is defined as the standard deviation of the original distribution upon root of the sample size.

i.e.

Therefore, The standard error of the mean is 0.85.

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

24+x=y
