Question

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; ther compare the variation. Male 90 72 60 70 71 53 62 52 82 70 63 64 98 58 65 Female 65 84 81 69 73 83 89 87 88 89 92 71 90 79 79 The coefficient of variation for the male pulse rates is 1 % Type an integer or decimal rounded to one decimal place as needed.) The coefficient of variation for the female pulse rates is Џ96 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. more than 5 percentage points apart within 5 percentage points of each other.
