Answer:
Step-by-step explanation:
For this case we have a sample of n =10 and we have the following statistics:
And we want to estimate the population variance. We need to remember that the population variance is given by this formula:
And the sample variance is given by:
And we can find a formula for the population variance in terms of the sample deviation like this:
And replacing we got:
The answer is 50.24
C=2Лr
C=16Л
C=50.24
Yes you can!!!!!!!!!!!
D. 2x - 2 + 3x
First, add 2x and 3x. Then you get 5x. Then you get the equivalent expression 5x-2.
