Complete the chart to find the mean, variance, and standard deviation. Remember to use commas and round numbers to the nearest tenth. X

X

X - X

(X - X )2

1. 45 = -357.5 = The mean is

2. 340 = -62.5 = The variance is

3. 400 = -2.5 = The standard deviation is

4. 825 = 422.5 = n =

Σ X = X = Σ (X - X)2 = 310,225.2

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
