Question

Please help don’t understand at alll

Answer 1

47.3

Explanation:

To find the standard deviation use this example formula

`a =\sqrt{((x-u)^(2) )/(N) }`

a = your answer, the standard deviation you are looking for

x = the value of each carrier

u = the carrier numbers mean (such as mean, median, and mode)

N = the overall total of the carriers

If you find this equation still confusing one of my favorite sites to use is Math.way, where you plug in each number with a comma in between and it solves it for you. Other sites work such as Calculatornet, Calculator.Soup, and Math.is.Fun.

Hope this helps :)
