question:    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. In the paper, “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. 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 blood pressures obtained prior to intervention for the 41 bus drivers in the study.

A)    Exploratory Data Analysis

b.     Investigate the data for definite outliers. Drop all definite outliers from the set and redo part a.

c.     Summarize the data set using a table of descriptive statistics. The table must be generated by a statistical software and include the following statistics:

                                              i.     The number of observations in data set

                                            ii.     Mean

                                          iii.     Median

                                          xii.     Standard error of the mean

B)    Inferential Statistics

a.    Use a STATISTICAL SOFTWARE to construct a 90% confidence interval for µ, the population mean diastolic blood pressure of all urban bus drivers in Stockholm.

b.    In adults the ideal diastolic blood pressure is 80 mm Hg.  At the 5% significance level, do the data provide sufficient evidence to conclude that the mean diastolic blood pressure of bus drivers in Stockholm exceeds the normal diastolic blood pressure of 80 mm Hg? Have Software conduct the appropriate test. Using the softwareoutput, perform the full hypothesis test.


C)    Project Summary & Findings

a.    Write a brief introductory paragraph regarding the background of data.

b.    Write paragraph (or two) that specifies the shape of the distribution of the data and reference your graph(s) used to make your decision.
