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

Class |
frequency |

40-50 |
2 |

50-60 |
10 |

60-70 |
16 |

70-80 |
8 |

80-90 |

From Excel

> enter the data in excel sheet

> select the dada

> go to insert

> select histogram

Yes, the given data is normally distributed. Because from the graph is roughly bell shaped.
