H0 : μ1 = μ2 H1 : μ1 ≠ μ2 A random sample of 10 observations from one population revealed a sample mean of 22 and a sample standard deviation of 3.7. A random sample of 7 observations from another population revealed a sample mean of 26 and a sample standard deviation of 5.0. 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: a. State the decision rule. (Negative amounts should be indicated by a minus sign. Round your answer to 3 decimal places.) b. Compute the pooled estimate of the population variance. (Round your answer to 3 decimal places.) c. Compute the test statistic. (Negative amount should be indicated by a minus sign. Round your answer to 3 decimal places.) d. State your decision about the null hypothesis. multiple choice 1 Reject H0. Do not reject H0. e. The p-value is multiple choice 2 between 0.1 and 0.05. less than 0.001. between 0.02 and 0.05. between 0.001 and 0.01. between 0.1 and 0.2.
