Let P1= proportion of sales representatives who are comfortable in cold calling (answered "Yes") before the training, P2= proportion of sales representatives who are comfortable in cold calling (answered "Yes") after the training What would be the alternative hypothesis for testing whether the sales training program is effective in that there is an increase in the proportion of sales representatives who are comfortable in cold calling after the training? Submit Show Table A. P1 is equal to P2 B. P1 is not equal to P2 C. P1 is greater than P2 D. 0.3706
