The null and alternate hypotheses are: H0 : μ1 = μ2 H1 : μ1 ≠ μ2 A random sample of 8 observations from one population revealed a sample mean of 23 and a sample standard deviation of 2.5. A random sample of 9 observations from another population revealed a sample mean of 25 and a sample standard deviation of 1.3. The population standard deviations are unknown but assumed to be equal. At the 0.05 significance level, is there a difference between the population means?
