Resting Pulse: earlier this semester we determined our resting pulse. Seventy-nine individuals participated in this data collection. The mean heart rate for all individuals was 65.34 beats per minute. A random sample of 30 heart rates having a mean of 64.97 beats per minute is presented here. Build a frequency table of these data containing six (6) classes with the lower llimit of the second class at 54 beats per minute. Build a chart appropriate for the presentation of these data. Data: 49, 51, 53, 56, 57, 58, 60 , 60, 62, 62, 62, 64, 64 65, 65 , 65, 67, 68, 68, 68, 69, 70 , 70, 72, 72, 72, 72, 75, 75 , 78,
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.

A) The mean and median are about equal because the distribution is right‑skewed. B) The mean is larger than the median because the distribution is right‑skewed. C) The median is larger than the mean because the distribution is right‑skewed. D) There is not enough information to tell us about the relationship between the mean and median in the histogram. (c) In general, you cannot find the exact values of median, quartiles, or mean from the histogram. What is special about the histogram of the number of servings of fruit that allows you to do this?
