Section 10.4 Summary

1. In this section, we learn how to perform hypothesis tests regarding two population standard deviations, using a new distribution called the distribution. The tables can be used to find critical values of the distribution.
2. The test for comparing two population standard deviations may be performed using the critical-value method, where the test statistic is compared with the critical value(s) of the distribution.
3. The test may also be performed using the -value method, where the -value is compared with the level of significance .
