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: 9, 8, 8, 8, 3 B: 10, 2, 8, 10, 5, 6, 5 Question content area bottom Part 1 a) What are the sample standard deviations? sSubscript Upper Aequals enter your response here (Do not round until the final answer.
