The null and alternate hypotheses are: Ho =P HP P A random sample of 8 observations from one population revealed a sample mean of 23 and a sample standard deviation of 4.6. A random sample of 8 observations from another population revealed a sample mean of 27 and a sample standard deviation of 4.6. The population standard deviations are unknown but assumed to be equal. At the 0.01 significance level, is there a difference between the population means? Required: 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 Ho if t or f 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.)
