For numbers 28 and 29. Consider: The coefficient of variation of the height of 20 people selected at random from a given city is found to be 15%. The weight of the selected group has a mean value 72 kg and a standard deviation 8 kg. 28. The coefficient of variation for the weight of the selected group is A. 11.11 B. 8.33% C. 11.11% D. 8.33 29. The obtained results show that A. the weight is more variable than height. B. the weight is less variable than height. C. height and weight have the same degree of variation. D. height and weight are independent. For numbers 28 and 29. Consider: The coefficient of variation of the height of 20 people selected at random from a given city is found to be 15%.
