Another similar study is to be undertaken to compare the mean posttest scores for BACC and traditionally taught high school biology students. The objective is to produce a 99% confidence interval for the true difference in the mean posttest scores. If we need to sample an equal number of BACC and traditionally taught students and want the width of the confidence interval to be 1.0, how many observations should be included in each group
