4. [-/1 Points] DETAILS ASWESBE9 11.E.015. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER You may need to use the appropriate technology to answer this question. Consider the following hypothesis test. 612- 02- Ho: 1 2 + 67 Ha: 1" (a) What is your conclusion if nj = 21, s, 2 = 4.2, n2 - 26, and s2? = 2.07 Use a = 0.05 and the p-value approach. Find the value of the test statistic. Find the p-value. (Round your answer to four decimal places.) p-value = State your conclusion. Reject Ho. We cannot conclude that o, 2 + 622. Do not reject Ho. We cannot conclude that a, 2 # #2 2. Reject Ho. We can conclude that 12 # 62. Do not reject Ho. We can conclude that a1 2 . 62 2. (b) Repeat the test using the critical value approach. Find the value of the test statistic. State the critical values for the rejection rule. (Round your answers to two decimal places. If you are only using one tail, enter NONE for the unused tail.) test statistic s test statistic 2 State your conclusion. Reject Ho. We cannot conclude that o, 2 + 622. Do not reject Ho. We cannot conclude that a12 . #22. O Reject Ho. We can conclude that o 1 2 # 622. Do not reject Ho. We can conclude that 12 + 62
