Question: Refer to Data Set 22 in Appendix B for the
Refer to Data Set 22 in Appendix B for the axial loads of aluminum cans that are 0.0111 in. thick. The load of 504 lb is an outlier because it is very far away from all of the other values. Construct a frequency distribution that includes the value of 504 lb, and then construct another frequency distribution with the value of 504 lb excluded. In both cases, start the first class at 200 lb and use a class width of 20 lb. State a generalization about the effect of an outlier on a frequency distribution.
Answer to relevant QuestionsAccording to what is known as Sturges’ guideline, the ideal number of classes for a frequency distribution can be approximated by 1 + (log n)/(log 2)where n is the number of data values. Use this guideline to complete ...What is a reasonable explanation for the gap between the group of people with heights between 43 in. and 55 in., and the group of people with heights between 57 in. and 77 in.? Constructing Histograms. In Exercises 9–18, ...Use the frequency distribution from Exercise 25 in Section 2-2 to construct a histogram. Using a very loose interpretation of the requirements for a normal distribution, do the red blood cell counts appear to be normally ...Refer to Data Set 12 in Appendix B, and use the heights of U.S. Presidents and the heights of their main opponents in the election campaign. Does there appear to be a correlation? Construct a scatter plot. Refer to Data Set 14 in Appendix B and use the 21 braking distances (ft). Are there any outliers? Is there strong evidence suggesting that the data are not from a population having a normal distribution? Pareto Charts. In ...
