Suppose we take a sample of 18 men and 17 women to estimate the difference in average height between men and women. The men had an average height of 70 inches with a standard deviation of 3, and the women had an average height of 66 inches with a standard deviation of 2. Calculate the pooled sample variance (Sp^2) for a two-sample confidence interval for the difference in means.
