The number of employees who showed up to work on-time was recorded over the previous month. Each office is then required to administer the new program. The number of employees who showed up to work on-time at each location one month after the training is recorded. Using the summary information below, determine the paired t-test test statistic for the research hypothesis that the training program increased on-time attendance. (Define the difference as After - Before). = 7, sd= 10
