The null and alternate hypotheses are H0 1 2 H1 1 2 A ran

The null and alternate hypotheses are: H0 : 1 = 2 H1 : 1 2 A random sample of 9 observations from one population revealed a sample mean of 22 and a sample standard deviation of 4.7. A random sample of 9 observations from another population revealed a sample mean of 26 and a sample standard deviation of 3.6. At the 0.10 significance level, is there a difference between the population means? a. State the decision rule. (Negative amounts should be indicated by a minus sign. Round your answer to 3 decimal places.) The decision rule is to reject H0 if t < or t > . b. Compute the pooled estimate of the population variance. (Round your answer to 3 decimal places.) Pooled estimate of the population variance c. Compute the test statistic. (Negative amount should be indicated by a minus sign. Round your answer to 3 decimal places.) Test statistic d. State your decision about the null hypothesis. H0 . e. The p-value is .
