The Excel file Accounting Professional Problem #27, P. 278: Remember to omit b Explanation for Part a: (Example) ANSWER: Ho: Uy - UN O meaning that the average time it takes students in programs paid by employers (Yes) is greater than the time it takes students in programs paid out of their oven funds (No). This is a right-tailed test. The t-statistic is 0.648, the level of significance is .05, the critical value is 1.746, and the p- value is.263. Because the t-statistic does not fall in the critical region and because p> a (.263 > .05) we fail to reject the null hypothesis. The data do not suggest that the average completion time it takes students whose employers pay for their nursing continuing education programs is longer than the average completion time of students who pay for those programs themselves. Explanation for Part c: YOUR EXPLANATION ANSWER: Ho: Uy - UNO implies that
