A company that produces financial accounting software wants to offer better training to its customers.The training is intended to decrease the amount of time required to do complicated accounting calculations.For seven individuals,the amount of time (in minutes)to complete a complicated calculation is determined before and after completing the new training. Using the p-value approach and α = 0.05,the appropriate conclusion is _________.
A) do not reject the null hypothesis;we cannot conclude the median difference of the times is greater than zero
B) do not reject the null hypothesis;conclude the median difference of the times is greater than zero
C) reject the null hypothesis;we cannot conclude the median difference of the times is greater than zero
D) reject the null hypothesis;conclude the median difference of the times is greater than zero

Based on the p-value approach and α = 0.05, if the p-value is greater than 0.05, we do not reject the null hypothesis. In this case, the p-value is not given, so we cannot calculate it. Therefore, the appropriate conclusion is that we do not reject the null hypothesis, which means we cannot conclude the median difference of the times is greater than zero.
