You are looking for a way to incentivize the sales reps that you are in charge of. You design an incentive plan as a way to help increase in their sales. To evaluate this innovative plan, you take a random sample of your reps, and their weekly incomes before and after the plan were recorded. You calculate the difference in income as (after incentive plan - before incentive plan). You perform a paired samples t-test with the following hypotheses: Null Hypothesis: uD = 0, Alternative Hypothesis: up 0. You calculate a pvalue of 0.285. What is the appropriate conclusion of your test? 0 1) The average difference in weekly income is equal to 0. O 2) The average difference in weekly income is significantly different from 0. There is a significant difference in weekly income due to the incentive plan. 0 3) We did not find enough evidence to say there was a significantly negative average difference in weekly income. The incentive plan does not appear to have been effective. 0 4) We did not find enough evidence to say there was a significantly positive average difference in weekly income. The incentive plan does not appear to f) have been effective. 0 5) We did not find enough evidence to say the average difference in weekly income was not 0. The incentive plan does not appear to have been effective
