A medical examiner believes that the distribution of men and women are identical when recording the number of illnesses over a year as opposed to the distributions being different. A random sample of 300 individuals is taken and a large-sample Wilcoxon Rank Sum Test is conducted. Sample 1 consists of males with n = 107 and the sum of ranks for that sample equaling 14,059.5. Sample 2 consists of females with n = 193 and the sum of ranks for that sample equaling 31,090.5. Conduct the two-tailed hypothesis test at the 0.05 level. Do not show your work, but report the value of the mean, the value of the standard deviation, the value of the z test statistic, the decision rule, and the final test results.
