Question

A sample of 16 items from population 1 has a sample variance s1^2 = 5.9 and a sample of 20 items from population 2 has a sample variance s2^2 = 2.3. Test the following hypotheses at the 0.05 level of significance. H0 : ?1^2 ? ?2^2 Ha : ?1^2 > ?2^2 a. What is your conclusion using the p-value approach? Calculate the value of the test statistic (to 2 decimals). The p-value is - Select your answer -. Use Table 4 of Appendix B. What is your conclusion? - Select your answer - 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 H0 if F - Select your answer - . What is your conclusion? - Select your answer - that population 1 show a greater variation.
