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:

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine

u dumb boi
