Question

I Need Help Please ASAP. I have been stuck for more than an hour.

Find the standard deviation of the given data rounded to the nearest hundredth. 147, 141, 120, 124, 128​

Answer 1

the mean is 132. (the average of all the numbers)

to find standard deviation:

[(147-132)^2 + (141-132)^2 + (120-132)^2 + (124-132)^2 + (128-132)^2 ] ALL OVER 5

you get 106 then square root it to get 10.29563014
