Problem 11BSC
Constructing Histograms. In Exercises, construct the histograms and answer the given questions.
Pulse Rates of Males Use the frequency distribution from Exercise 1 in Section to construct a histogram. Does the histogram appear to depict data that have a normal distribution? Why or why not?
Exercise 1
Constructing Frequency Distributions. In Exercise, use the indicated data and construct the frequency distribution.
Pulse Rates of Males Refer to Data Set 1 in Appendix B and use the pulse rates (beats per minute) of males. Begin with a lower class limit of 40 and use a class width of 10. Do the pulse rates of males appear to have a normal distribution?
Answer :
Step 1 of 1 :
Given , the pulse rates (beats per minute) of males.
The class width is 10
