Independent random samples were selected from two normally distributed populations. Given n1 =7 from population 1 and n2=9 from population 2.

Population 1: 2.5, 3.1, 2.3, 1.8, 4.2, 3.5, 3.9

Population 2: 2.9, 1.7, 4.6, 3.5, 3.7, 2.8, 4.6, 3.4, 1.9

Find the test statistic for H0 = σ2 = σ2 against HA = σ2 ≠σ2

    Recent research indicates that the effectiveness of antidepressant medication is directly related to the severity of the depression (Khan, Brodhead, Kolts & Brown, 2005). Based on pretreatment depression scores, patients were divided into four groups based on their level of depression. After receiving the antidepressant medication, depression scores were measured again and the amount of improvement was recorded for each patient. The following data are similar to the results of the study. Low Moderate High Moderate Moderately Severe Severe 1.2...

    Independent random samples, each containing 90 observations, were selected from two populations. The samples from populations 1 and 2 produced 50 and 42 successes, respectively. Test H0:(p1−p2)=0 against Ha:(p1−p2)≠0. Use α=0.04. (a) The test statistic is (b) The P-value is (c) The final conclusion is A. We can reject the null hypothesis that (p1−p2)=0 and accept that (p1−p2)≠0. B. There is not sufficient evidence to reject the null hypothesis that (p1−p2)=0. side note- no idea how to find a test...
