A clinical psychologist claims that social support increases causes depression symptoms to decrease. They want to test this experimentally by randomly assigning 89 students to receive additional social support and then assessing depression symptoms to find a mean of 34 and a standard deviation of 7. Another 100 students receive no additional social support and are assessed on their depression symptoms to find a mean of 76 and a standard deviation of 10. They plan to use mu1 - mu2, where Mi = mu1 = Additional social support and H2 = mu2 = No additional social support Please compute the weighted (or pooled) variance for your data to 4 decimal places.
