. Carefully read through the following data Previous studies have shown that urban bus drivers have an extremely stressful job, and a large proportion of drivers retire prematurely with disabilities due to occupational stress. These stresses come from a combination of physical and social sources such as traffic congestion, incessant time pressure, and unruly passengers. A study examined the effects of an intervention program to improve the conditions of urban bus drivers. Among other variables the researchers monitored diastolic blood pressure of bus drivers in downtown Stockholm, Sweden. The data, in millimeters of mercury (mm Hg), are based on the diastolic blood pressures obtained prior to intervention for a random sample of 25 bus drivers in the study. 81 74 88 65 90 89 93 73 70 80 79 85 75 83 99 94 90 81 93 79 95 95 73 83 63 (Adapted from "Hassles on the Job: A Study of a Job Intervention with Urban Bus Drivers" (Journal of Organizational Behavior, Vol. 20, pp. 199 - 208), G. Evans et al.) Use a statistical software package to complete the analysis of Exploratory Data Analysis and Inferential Statistics. You are encouraged to use StatCrunch (in MyStatLab) since your instructor can help you with this. You may also use any other software packages. However, if you use other software, you are on your own. A) Exploratory Data Analysis 1. Summarize the data using a stem and leaf display. 2. Summarize the data using a histogram with 5 classes. 3. Construct a boxplot and use it to investigate the data for outliers. 4. Summarize the data set using the sample mean, median, and standard deviation
