Refer to the sample data in Exercise 1.a. Given that each sample was generated from a uniform distribution of whole ?numbers between 1 and 1000, what is the median of each population?b. Suppose the Wilcoxon rank-sum test is used for the data in Exercise 1. Are ?we testing that each of the two samples is from a population with the median identified in part (a)?

Data from Exercise 1

Listed below are randomly selected values from STATDISK and the TI-83 84 Plus calculator. Both samples are obtained by selecting a uniform distribution of whole numbers between 1 and 1000 inclusive. When trying to test for a difference between the population of such random numbers from each of the two sources, which test should not be used: the parametric t test or the Wilcoxon rank-sum test? Why? STATDISK: 606 561 834 421 481 716 272 703 556 94 172
