The following is a set of data for a population with n = 10: 7 5 11 8 3 6 2 1 9 8

a. compute the population mean.

b. compute the population standard deviation.

a)

b)

Step-by-step explanation:

The population size is given N=10, and the data are:

7 5 11 8 3 6 2 1 9 8

Part a

The population mean for this case is given by this formula:

And if we replace we got:

Part b

And the population standard deviation is given by:

And if we replace we got:

step-by-step explanation:

the answer is 128

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.
