Answer» Here SD(Boys) is 3 and SD (girls) = 2 Coefficient variability = \(\frac{SD}{Mean}\times100\) Coefficient variance (Boys) = \(\frac{3}{60}\times 100\) Cv (Boys) = 5 Coefficient variance (Girls) = \(\frac{2}{45}\times 100\) Cv (Boys) = 5 Coefficient variance (Girls) = \(\frac{2}{45}\times 100\) Cv (Girls) = 4.4 Hence, Cv Boys is greater than Cv girls,then the distribution of weights of boys is more variable than that of girls |
