The null and alternate hypotheses are: Hi1i2:0 [him#27\") A random sample of 17 observations from the first population revealed a sample mean of 345 and a sample standard deviation of 13. A random sample of16 observations from the second population revealed a sample mean of 340 and a sample standard deviation of 12. At the 0.01 significance level, is there a difference in the population means? a. State the decision rule. (Negative answer should be indicated by a minus sign. Round the final answers to 3 decimal places.) The decision rule is to reject H0 if t This is a (Click to select) v -tailed test. b. Compute the pooled estimate of the population variance. (Round the final answer to 2 decimal places.) Pooled estimate of the population variance c. Compute the test statistic. (Round the nal answer to 3 decimal places.) The test statistic is: I\": d. What is your decision regarding H0? H0 is (Click to select] V . e. Estimate the pvalue. (Round the final answer to 4 decimal places.) The pvalue is|:|
