The null and alternate hypotheses are: h0 : μ1 = μ2h1 : μ1 ≠ μ2a random sample of 12 observations from one population revealed a sample mean of 25 and a sample standard deviation of 3.5. a random sample of 9 observations from another population revealed a sample mean of 30 and a sample standard deviation of 3.5.at the 0.01 significance level, is there a difference between the population means? state the decision rule.
a. state the decision rule. b. compute the pooled estimate of the population variance. c. compute the test statisticd. state your decision about the null hypothesis. e. the p-value is
