Will give a ! why does the formula use “n – 1” in the denominator? the data is a sample and is expected to be more dispersed from the mean. the data is a sample and is expected to be less dispersed from the mean. the data is a population and is expected to be more dispersed from the mean. the data is a population and is expected to be less dispersed from the mean.

Answer with explanation:

Formula to find variance of Population

Formula to find variance of a Sample

The meaning of the word Variance, is how dispersed the variate are from mean.

Option A

The data is a sample and is expected to be more dispersed from the mean.

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
