A researcher is interested in exploring factors that could be related to major disturbances in prisons. Specifically, they want to test the hypothesis that staffing levels affect security. The independent variable, staffing levels, is measured as the number of staff per 100 inmates and the dependent variable, security, is measured as the number of major disturbances in the past year. The following table contains data on these variables for a random sample of 10 prisons. Using a .01 level of significance, answer the following questions. Staff per 100 inmates 4 7 12 3 14 17 38 15 14 Major disturbances 0 0 1 2 3 1 0 2 0 c. Calculate the test statistic.
