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: 69 89 55 95 98 67 55 58 61 57 63 56 55 78 61 Female: 64 81 92 86 89 67 85 88 92 74 92 93 79 78 71 The mean for males is 67.8 beats per minute and the mean for females is 82.1 beats per minute. (Type integers or decimals rounded to one decimal place as needed.) Find the medians. The median for males is 61 beats per minute and the median for females is 85 beats per minute. (Type integers or decimals rounded to one decimal place as needed.) Compare the results. Choose the correct answer below. OA. The mean is lower for males, but the median is lower for females. OB. The median is lower for males, but the mean is lower for females. OC. The mean and the median for females are both lower than the mean and the median for males. D. The mean and the median for males are both lower than the mean and the median for females. OE. The mean and median appear to be roughly the same for both genders. Does there appear to be a difference? OA. The pulse rates for males appear to be higher than the pulse rates for females. B. The pulse rates for females appear to be higher than the pulse rates for males. OC. There does not appear to be any difference. D. Since the sample size is small, no meaningful information can be gained from analyzing the data.

there appear to be a difference?
Male: 69 89 55 95 98 67 55 58 61 57 63 56 55 78 61
Female: 64 81 92 86 89 67 85 88 92 74 92 93 79 78 71
The mean for males is 67.8 beats per minute and the mean for females is 82.1 beats per minute.
(Type integers or decimals rounded to one decimal place as needed.)
Find the medians.
The median for males is 61 beats per minute and the median for females is 85 beats per minute.
(Type integers or decimals rounded to one decimal place as needed.)
Compare the results. Choose the correct answer below.
OA. The mean is lower for males, but the median is lower for females.
OB. The median is lower for males, but the mean is lower for females.
OC. The mean and the median for females are both lower than the mean and the median for males.
D. The mean and the median for males are both lower than the mean and the median for females.
