Hello, I need help with question a. only. Thank you!

Exercise 11.15 Algo (Inferences About Two Population Variances) Consider the following hypothesis test. H. : 01 7 03 a. What is your conclusion if m1 = 21, s, = 8.8, ny = 26, and s? = 4. Use a = 0.05 and the p-value approach. Calculate the value of the test statistic (to 2 decimals). The p-value is between 0.05 and 0.10 # . Use Table 4 of Appendix B. What is your conclusion? Cannot conclude that the two population variances are different * 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 greater than or equal to 2.30 What is your conclusion? Cannot conclude that the two population variances are different ;TABLE 4 F DISTRIBUTION Area or probability Fa Entries in the table give F. values, where a is the area or probability in the upper tail of the F distribution. For example, with 4 numerator degrees of freedom, 8 denominator degrees of freedom, and a .05 area in the upper tail, Fos = 3.84.
