A random sample of size n 1 equals 31 results in a sample mean of 123.3 and a sample standard deviation of 8.5. An independent sample of size n 2 equals 50 results in a sample mean of 129.8 and sample standard deviation of 7.3. Does this constitute sufficient evidence to conclude that the population means differ at the alpha equals 0.01 level of significance?
