Step-by-step explanation:
The difference in the formula of population and sample variance can be explained as:
Population variance is said to be the value of variance that is calculated from population data, whereas sample variance refers to the variance calculated from sample data. This is the reason why value of denominator in the formula for variance in case of sample data is ‘n-1’, while it is ‘n’ for population data. Hence, the result of both variance and standard deviation derived from sample data is larger than those found out from population data.
The correct answer is Choice B.
The first step in this problem is to divide both sides by 64.
On the left side, you will have b squared.
On the right side, you will have 1/4.
Now, take the square root of both sides.
The square root of 1/4 is positive or negative 1/2.
Bob the numerator and denominator are divisible by 3 so the simplified fraction would be 9/17
