Determine the standard deviation of the data below. (1, 2, 3, 4, 5)

a) √2
b) 3
c) 2

sqrt(2)

Step-by-step explanation:

1. Find the mean.

Mean=1+2+3+4+5=15/5=3

2. Subtract each number by the mean and square the value.

1-3=-2^2=4

2-3=-1^2=1

3-3=0^2=0

4-3=1^2=1

5-3=2^2=4

3. Add the values in step 2 then divide by amount of numbers.

4+1+0+1+4=10/5=2

4.Square the value in step 3 and that is the answer.

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
