A sample of 50 observations is selected from one population with a population standard deviation of 3 . The sample mean is 102 . A sample of 50 observations is selected from a second population with a population standard deviation of 7. The sample mean is 99 . Conduct the following test of hypothesis using the 0.01 significance level: H0:12=0 H1:12=0 a. Is this a one-tailed or a two-tailed test? b. State the decision rule. (Negative answer should be indicated by a minus sign. Round the final answers to 2 decimal places.) The decision rule is to reject H0 if z is the interval ( (8). c. Compute the value of the test statistic. (Round the final answer to 2 decimal places.) Value of the test statistic d. What is your decision regarding H0 ? H0 e. What is the p-value? (Round the z-value to 2 decimal places. Round the final answer to 4 decimal places.) The p-value is
