Question

identify how to calculate the standard deviation or variation of a data set. the mean cost for a pint of frozen yogurt is $1.50, with a standard deviation of $0.10. what is the value of the variance? a.) $0.10 b.) $0.40 c.) $0.20 d.) $0.01

Answer 1

The variance of the cost of a pint of frozen yogurt is calculated by squaring the standard deviation of $0.10. The variance comes out to be $0.01.

Step-by-step explanation:

To calculate the variance of a data set, we square the standard deviation. In this case, since the standard deviation is $0.10, we calculate the variance by squaring $0.10:

Variance = (Standard Deviation)^2

Variance = ($0.10)^2

Variance = $0.01

Therefore, the value of the variance for the cost of a pint of frozen yogurt is $0.01, which corresponds to option d.) $0.01.
