    Hypothesis Test

    It is assumed that the life of the bulbs is normally distributed test the null hypothesis that the samples were obtained from populations with equal variance, considering \alpha = 10%, considering the following information:
    n_1 = 10 n_2=8
    S_1 = 200 S_2=62500

    You need to test that there is no difference in mean bulb life between the 2 populations

    H_0: \mu_1 = \mu_2

    H_a: \mu_1 \neq \mu_2

    Now use a t-test for difference in means.

    Are you firmiliar with this test?

    You are testing the variances for equality so you should use the variance ratio or F-test.
