Part 1 of 3 Points: 0 of 1 Listed below are pulse rates (beats per minute) from samples of adult males and females. Does there appear to be a difference? Find the coefficient of variation for each of the two samples, then compare the variation. Male 87 72 62 70 69 52 62 54 84 72 61 60 97 57 62 Female 68 81 78 71 76 82 86 88 87 90 92 69 90 80 77 The coefficient of variation for the male pulse rates is% (Type an integer or decimal rounded to one decimal place as needed.)
