Consider the following data to determine whether there is a significant difference between the values of Group 1 and Group 2. Let the significance level be 5%. Group 1: 15, 17, 26, 11, 18, 21, 13, 29 Group 2: 23, 14, 24, 13, 22, 23, 18, 21 What rank will be given to the value 15? What is the rank sum, W1, of Group 1? (round answer to 1 decimal place) What is the value of the test statistic, U? (round answer to 1 decimal place) Using the Mann Whitney Table of p-values, what is the p-value for this test? Round your U test statistic up to the next value to locate on the table. (round answer to 4 decimal places)
