Suppose you are to test the mean difference between two independent samples in your data. The (unbiased) standard deviation in the first sample is 15, and it is 12 in the second sample. The sample sizes are 50 for the first and 100 for the second. Calculate the numerator of the pooled variance (numerator only, not the pooled variance itself).
