The IQs of 25 CEGEP students were measured before and after a six month quarantine because of the novel corona virus. The mean of the before scores was mBefore = 109.5 and the mean of the after scores was mafter = 102.6. The variance of the difference scores was 64. Compute the lower limit of the approximate 95% confidence interval around the estimated effect size computed with mBefore– mAfter in the numerator.
