**Educational Text Transcription:**Use the following data sets in problems #4-#6.**Data Set 1:** A genetic study was performed on stickleback fish. A random sample of 40 stickleback fish showed the following number of armored plates found on stickleback fish:| | | | | ||---|---|---|---|---|| 12 | 54 | 52 | 52 | 54 || 52 | 61 | 63 | 52 | 49 || 54 | 21 | 62 | 42 | 9 || 51 | 60 | 30 | 35 | 57 || 27 | 24 | 55 | 49 | 50 || 53 | 58 | 48 | 61 | 53 || 55 | 62 | 50 | 50 | 50 || 51 | 27 | 60 | 12 | 54 || 12 | 11 | 10 | 62 | 62 |**Data Set 2:** It has been hypothesized that the body temperature of healthy adult humans is normally distributed. A random sample of 25 healthy adults resulted in the following body temperatures:| | | | | ||---|---|---|---|---|| 98.6 | 99.4 | 98.5 | 98.3 | 98.4 || 98.8 | 99.3 | 99.2 | 99 | 98.3 || 97.5 | 98.2 | 98.6 | 98.9 | 99.3 || 98.6 | 98.9 | 99.1 | 98.2 | 98 || 97.8 | 98.5 | 98.2 | 99 | 98.8 |**Questions:**4. For each of the data sets, calculate the mean and median. Based on the mean and median, what is the most likely distribution of each data set?5. Construct a stem-and-leaf plot and a boxplot for each data set.6. Do the graphs in #5 support your answers to #4? Justify your answer using a complete sentence(s) and proper grammar.

How long did real cowboys live? One answer may be found in the book The Last Cowboys by Connie Brooks (University of New Mexico Press). This delightful book presents a thoughtful sociological study of cowboys in West Texas and Southeastern New Mexico around the year 1890. A sample of 32 cowboys gave the following years of longevity: 58 52 68 86 72 66 97 89 84 91 91 92 66 68 87 86 73 61 70 75 72 73 85 84 90 57 77 76 84 93 58 47 (a) Make a stem-and-leaf display for these data.

ch 11 end. 5 : The XYZ Corporation is interested in possible differences in days worked by salaried employees in three departments in the financial area. A survey of 23 randomly chosen employees reveals the data shown below. Because of the casual sampling methodology in this survey, the sample sizes are unequal. Research question: Are the mean annual attendance rates the same for employees in these three departments?
