Question

Listed below are pulse rates (beats per minute) from samples of adult males and females. Find the mean and median for each of the two samples and then compare the two sets of results. Does there appear to be a difference? Male: 67 54 54 86 77 55 62 61 64 57 59 88 63 76 69 Female: 90 79 87 88 68 63 93 87 87 84 66 89 72 89 74 Find the means. The mean for males is beats per minute and the mean or females is (Type integers or decimals rounded to one decimal place as needed.) Find the medians. beats per minute The median for males is beats per minute and the median for females is Type integers or decimals rounded to one decimal place as needed.) Compare the results. Choose the correct answer below. beats per minute OA. The mean and the median for males are both lower than the mean and the median for females O B. The median is lower for males, but the mean is lower for females. O C. The mean and the median for females are both lower than the mean and the median for males O D. The mean and median appear to be roughly the same for both genders. O E. The mean is lower for males, but the median is lower for females. Does there appear to be a difference? OA Since the sample size is small, no meaningful information can be gained from analyzing the data O B. There does not appear to be any difference. O C. The pulse rates for females appear to be higher than the pulse rates for males. D. The pulse rates for males appear to be higher than the pulse rates for females.
