Question

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 last 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
x rank	2	4	5	3	7	9
y rank	3	6	5	8	9	11

Person	7	8	9	10	11
x rank	10	1	6	8	11
y rank	10	1	4	7	2

Using a 10% level of significance, test the claim that the relation between x and y is monotone (either increasing or decreasing). Estimate the P-value.
