A random sample of size n = 50 results in a sample mean of 21 and a sample standard deviation of 1.5. Anindependent sample of size n = 60 results in a sample mean of 19 and a sample standard deviation of 1.9. Doesthis constitute sufficient evidence to conclude that the population means differ at the α = 0.05 level ofsignificance?
