Training Program: Sales A data-processing company has a training program for new salespeople. After completing the training program, each trainee is ranked by his or her instructor. After a year of sales, the same class of trainees is again ranked by a company supervisor according to net value of the contracts they have acquired for the company.

The results for a random sample of 11 salespeople trained in the previous year follow, where x is rank in training class and y is rank in sales after 1 year. Lower ranks mean higher standing in class and higher net sales.

Person 1 2 3 4 5 6 7 8 9 10 11 x rank 6 8 11 2 5 7 3 9 1 10 4 y rank 4 9 10 1 6 7 8 11 3 5 2 Using a 0.05 level of significance, test the claim that the relation between x and y is monotone (either increasing or decreasing).
