Normal Distribution Refer to the frequency distribution given in Exercise 7 and ignore the given frequencies. Assume that the first three frequencies are 2, 12, and 18, respectively.

Assuming that the distribution of the 153 sample values is a normal distribution, identify the remaining four frequencies.

12.Normal Distribution Refer to the frequency distribution given in Exercise 8 and determine whether it appears to be a normal distribution. Explain.

13.Pulse Rates of Males Refer to Data Set 1 “Body Data” 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
