You conduct a study to assess whether the introduction of three-day weekends has an effect on workplace productivity. To do this, you assess the workplace productivity of 36 employees after they return from a standard two-day weekend, and again after they enjoy an extended three-day weekend. You obtain an average difference score of -2.40 between the conditions, with a variance of 10.24. Assuming that the null hypothesis outlines an average difference of zero, what is the appropriate test statistic? O A. -8.57 O B. -4.53 OC-0.14 D.-1.40
