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 90 71 62 70 69 50 64 54 84 70 60 60 100 57 64 Female 64 81 80 70 72 85 87 84 86 89 93 72 87 78 77 The coefficient of variation for the male pulse rates is nothing%. (Type an integer or decimal rounded to one decimal place as needed.) The coefficient of variation for the female pulse rates is nothing%. (Type an integer or decimal rounded to one decimal place as needed.) Compare the variation. The coefficients of variation for each data set are ▼ Therefore, the male pulse rates vary ▼ the female pulse rates.
