Question

Consider the following hypothesis test. H0 : ?1² = ?2² Ha : ?1² ? ?2² a. Suppose n1 = 21, s1² = 8.4, n2 = 26, and s2² = 4. Use ? = 0.05 and the p-value approach. Calculate the value of the test statistic (to 2 decimals). The p-value is between .05 and .10 . Use Table 11.1. 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 H0 if F greater than or equal to What is your conclusion? Cannot conclude that the two population variances are different

Ha : ?1² ? ?2²
a. Suppose n1 = 21, s1² = 8.4, n2 = 26, and s2² = 4. Use ? = 0.05 and the p-value approach.
Calculate the value of the test statistic (to 2 decimals).
The p-value is between .05 and .10 . Use Table 11.1.
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 H0 if F greater than or equal to
What is your conclusion?
Cannot conclude that the two population variances are different
