The variance of the sample means that is found in the sample distribution that we have here is 0.3333
This is the measure of dispersion that is used to show the spread of the data that is contained in a data set
The formula that we are to use here is given as
b² - a² / b - a
we have to put the values in this question
(14 - 2)² / 14 - 2
= 144 / 12
= 12
From here we would have to solve for the variance.
The variance = 12 / 35
= 0.3333
Hence the variance that we have in the question is equal to 0.3333
