To find the variance given the coefficient of variation (CV) and the mean, we can use the following relationship: The formula for the coefficient of variation (CV) is given by: CV=‌
σ
µ
×100 where σ is the standard deviation and µ is the mean. In this problem, the coefficient of variation is 25 , and the mean (µ) is 44 . Substituting these values into the equation, we have: ‌
σ
44
×100=25 Solving for σ, we get: σ=‌
25×44
100
=11 The variance (σ2) is the square of the standard deviation: σ2=112=121 Therefore, the variance is 121 .
