    1. H0: Σ 2 <= 22
    Ha: Σ 2 > 22

    A sample of 29 ages from a normal population yields a sample variance of 32.9. You want to test the following hypothesis using &#945;=.025

    What is the test statistic?
    What is the critical value?

    2. H0: Σ 2 >= 24
    Ha: Σ 2 < 24

    A sample of 28 ages from a normal population yields a sample variance of 18.4. You want to test the following hypothesis using &#945;=.025

    What is the test statistic?
    What is the critical value?
