If the sample standard deviation for the number of new vehicles sold per month for a sample of 6 car dealerships is 4.2, what is the variance for this set of data

the variance for this set of data is 17.64

Step-by-step explanation:

The computation of the variance for the set of data is as follows;

The variance is the square of the standard deviation

The standard deviation is 4.2

The variance is

= 4.2^2

= (4.2) (4.2)

= 17.64

Hence, the variance for this set of data is 17.64

Therefore the same is to be considered

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

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
