Question 1. Atwo-sample test for means was conducted to determine if the completion time for continuing education programs for nurses differed when costs are paid by employers(Yes) versus when individuals paid out of their own funds(No). The Excel Data Analysis tool results are provided. Complete parts a through c below. LOADING... Click the icon to view the Excel Data Analysis tool results. Question content area bottom Part 1 a. Explain how to use this information to draw a conclusion if the null hypothesis is H0: YN0. Clearly state the correct critical value andp-value and your conclusion. The alternative hypothesis is H1:

mu Subscript Upper Y Baseline minus mu Subscript Upper N Baseline less than 0.YN<0. mu Subscript Upper Y Baseline minus mu Subscript Upper N Baseline not equals 0.YN0. mu Subscript Upper Y Baseline minus mu Subscript Upper N Baseline greater than 0.
