Since 3.3062 < 4.462, fail to reject Ho and conclude equal variances so can use pooled standard deviation. Ho: μ1 – μ2 < 0. Ha: μ1 – μ2 > 0. df = 12 + 12 – 2 = 22. Using Excel’s average and stdev functions students can determine the sample mean and sample standard deviation of each of the samples. Sample 1: Sample 2: ................
