Exercise 11-7 (Algo) (LO11-2) The null and alternate hypotheses are: He : P1 - P2 HI. P1 - P2 A random sample of 11 observations from one population revealed a sample mean of 24 and a sample standard deviation of 1.3. A random sample of 5 observations from another population revealed a sample mean of 25 and a sample standard deviation of 1.5. The population standard deviations are unknown but assumed to be equal. At the 0.10 significance level, is there a difference between the population means? Required: . 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
