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 is rank in sales after 1 year Lower ranks mean higher standing in class and higher net sales 710132 Using a 5% level of significance, test the claim that the relation between x and yis monotone (either increasing or decreasing). Venly that the Spearman rank correlation coefficient ,-0.791 This implies that the P-value lies between 0.002 and 0.01 State the conclusion of the test and interpret your results with a 5% level of significance Since the P value is less than the given level of significance, the data are statistically significant Based on this, we do not reject the wall hypothesis. At the 546 level significance we conclude that there is insufficient evidence to indicate a monotone relationship (either increasing or decreasing) between rank sales Since the P-value is less than the given level of significance, the data are not statistically significant Based on this, we reject the null hypothesis. At the 5% level significance, we conclude that there is a monotone relationship (either increasing or decreasing) between rank sales Since the Preis greater than the given level of significance, the data are statistically significant. Based on this, we reject the null hypothesis. At the conclude that there is a monste relationship (either increase or decret) between rak sales level significance, we Since the P-value is less than the given level of significance, the data are statistically significant Based on this, we reject the mall hypothesis. At the 54 level significance, we conclude that there is a monotone relationship (either increasing or decreasing) between rank sales Since the P-value is greater than the given level of significance, the data are statistically significant. Based on this, we do not reject the null hypothesis. At the significance, we conclude that there is sufficient evidence to indicate a monotone relationship (either increasing or decrease between rank sales level ORI

Answer 1

Answer: Since the P-value is less than the give level of significance, the data are statistically significant. Based on this, we reject the null hypothesis. At the 5% level significance, we conclude that there is a monotone relationship (either increasing or decreasing) between rank sales.
