Trend of thinner beauty pageant winners has generated charges that the contest encourages unhealthy diet habits among young women Listed below are body indexes (BMI) for beauty pageant winners from two different time periods. Find the coefficient of variation for each of the two sets of data, then compare the coefficient of venation for the BMI\'s of beauty pageant winners from the 1920s and 1930s is % round to one decimal place as needed.) Solution Dear Student Thank you for usng Chegg !! Given Mean = (Sum of Values) / No of values Deviations = Values - Mean Variance = (Sum of square of deviations /no of deviations) Standard deviation (SD) = Square root of variance Coefficient of variation = Standard deviation / Mean BMI (B/w 1920 ~1930) Mean Deviations from mean Square (Deviations) Variance SD Coeff Of Variation BMI (From Recent Winners) Mean Deviations from mean Square (Deviations) Variance SD Coeff Of Variation 20.4 20.16 0.24 0.0576 1.9324 1.390108 0.068953765 19.5 18.76 0.74 0.5476 1.3004 1.140351 0.060786291 21.9 1.74 3.0276 20.3 1.54 2.3716 22.1 1.94 3.7636 19.5 0.74 0.5476 22.3 2.14 4.5796 20.2 1.44 2.0736 20.2 0.04 0.0016 17.8 -0.96 0.9216 18.8 -1.36 1.8496 17.9 - 0.86 0.7396 18.9 -1.26 1.5876 19.2 0.44 0.1936 19.4 -0.76 0.5776 18.9 0.14 0.0196 18.5 - 1.66 2.7556 17.6 -1.16 1.3456 19.1 -1.06 1.1236 16.7 -2.06 4.2436 Comparing the two Coefficient of variation 1920~1930 = 0.068953765 Recent = 0.060786291 Solved.
