Brainliest and the variance of a data set is 4. what is the standard deviation? show work a. 2 b. 4 c. 8 d. 16

The answer is 2

also  variance just means the squared difference meaning

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

two data sets with the same median will not have the same varaibility
