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.

PART I: For this part, we will divide the data set into two groups: those who have infection and those who do not. Consider only those who have an infection.1. For these subjects only, construct a stemplot for the variable “heart rate”. (We will be making this into a back-to-back stemplot later, so leave room on the left side.)2. Discuss the shape of your stemplot. Is it symmetric? Positively skewed? Negatively skewed? None of these? Are there any outliers?3. How would you describe the center and the spread of this distribution?4. Find the five-number summary.5. Construct a box plot.
