Consider the following hypothesis test. Ho: = H : 00 Ha a = 8.4, n = 26, and 8 = 4. Use = 0.05 and the p-value approach. s a. What is your conclusion if n = 21, s n2 Calculate the value of the test statistic (to 2 decimals). The p-value is - Select your answer What is your conclusion? - Select your answer- . Use Table 4 of Appendix B. b. Repeat the test using the critical value approach. What is the rejection rule for this hypothesis test? Round the critical values to 2 decimal places. Reject Ho if F - Select your answer - What is your conclusion? - Select your answer-
