a) standard deviation =

b)coefficient of variation =

c) which sample has the higher dispersion =

d) which sample has the higher relative dispersion =

Two samples are given. Find each sample's a) standard deviation and b) coefficient of variation. Then decide c) which sample has the higher dispersion, and d) which sample has the higher relative dispersion. A: 4,5,6,9,9 B:11,5,9,8,3,8,11 a) What are the sample standard deviations? SA= (Do not round until the final answer. Then round to the nearest hundredth as needed.) sB= (Do not round until the final answer. Then round to the nearest hundredth as needed.)
