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 86 72 62 69 72 50 65 55 83 70 61 63 96 58 66 Female 64 81 80 68 73 85 89 87 88 86 92 70 89 79 78 The coefficient of variation for the male pulse rates is (Type an integer or decimal rounded to one decimal place as needed.) The coefficient of variation for the female pulse rates is (Type an integer or decimal rounded to one decimal place as needed.) Compare the variation Therefore, the male pulse rates vary The coefficients of variation for each data set are (1) - (2) _ the female pulse rates. (1) O O within 5 percentage points of each other. more than 5 percentage points apart. (2) O about the same as O significantly more than O significantly less than
