Please Explain whats the difference between the two .

The resting heart rate of 60 patients is shown in the frequency table below. Heart Rate (beats per minute) Determine the standard deviation of the data set and explain what it means in terms of the data. I o The standard deviation is 9.27. The typical heart rate for the data set varies from the mean by an average of 9.27 beats per minute. I O The standard deviation is 13.69. The typical heart rate for the data set varies from the mean by an average of 13.69 beats per minute. I O The standard deviation is 9.27. The heart rate of a randomly selected patient varies from the mean by 9.27 beats per minute. I o The standard deviation is 13.69. The heart rate of a randomly selected patient varies from the mean by 13.69 beats per minute. The student populations of 10 colleges are shown. 28,457 29,290 31,730 35,351 41,710 47,122 47,966 49,589 58,698 174,000 Determine whether the mean or the median best describes the center of the data set and give its value. I o The mean best describes the center because the data are all close together. The mean is 54,391. I O The median best describes the center because the data are all close together. The median is 44,416. I O The mean best describes the center because it is not affected by an extreme value. The mean is 54,391. I o The median best describes the center because it is not affected by an extreme value. The median is 44,416
