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.

Develop a relative frequency distribution and a percent frequency distribution C. Lastly, present the quantitative data using Histogram (Open Data Analysis)
One of the primary goals of constructing a frequency distribution for quantitative data is to summarize the data O by showing frequency of values that lie within a class or bin. O so that there are always 7 classes or bins of data. O ensuring that the classes or bins are always of different widths. O in a manner so that each class or bin has the same number of data points.
