1. Frequency Distribution of Body Temperatures Construct a frequency distribution of the 20 body temperatures 1F2 listed below. (These data are from Data Set 2 "Body Temperatures" in Appendix B.) Use a class width of 0.5F and a starting value of 97.0F.

97.1 97.2 97.5 97.6 97.6 97.8 98.0 98.0 98.2 98.2 98.2 98.3 98.4 98.6 98.6 98.7 98.7 98.9 99.1 99.4

2. Histogram of Body Temperatures Construct the histogram that corresponds to the fre- quency distribution from Exercise 1. Use class midpoint values for the horizontal scale. Does the histogram suggest that the data are from a population having a normal distribution? Why or why not?

3. Dotplot of Body Temperatures Construct a dotplot of the body temperatures listed in Exercise 1. Which does a better job of illustrating the distribution of the data: the histogram from Exercise 2 or the dotplot?

4. Stemplot of Body Temperatures Constructs a stemplot of the body temperatures listed in Exercise 1. Are there any outliers?

5. Bears Listed below are the neck sizes (in.) and weights (lb) of bears (from Data Set 11 "Bear Measurements" in Appendix B). Construct a scatterplot. Based on the graph, does there appear to be a relationship between neck sizes and the weights of bears?

6. Monitoring Weight

a. After collecting the average (mean) weight of adult males in the United States for each of the most recent 100 years, we want to construct the graph that is most appropriate for these data. Which graph is best?

b. After collecting the average (mean) weight and height of males for the most recent 100 years, we want to construct a graph to investigate the association between those two variables. Which graph is best?

c. An investigation of health problems associated with overweight males includes heart dis-ease, stroke, high blood pressure, diabetes, and breathing problems. If we want to construct a graph that illustrates the relative importance of these adverse effects, which graph is best?
