You do not have to test the hypothesis for these questions. Possible Answers: Independent sample t-test with equal variance, independent sample t-test with unequal variance, dependent sample t-test, z-test for proportions, 1-way ANOVA, 2-way ANOVA Test whether income varies by relationship status and sex: married men (X = 55672, s = 13622), cohabiting men (X = 48924, s = 12789), single men (X = 42765, s = 9654), married women (X-49562, s = 15432), cohabiting women (X-41875, s 18709), and single women (X = 36891, s = 20761). E. F. Test whether the percent of college students who pulled all-nighters in the last week (P-0.32) is different from the percent of high school students who did (P-0.26). G. Test whether the number of accidents differs by type of licenses: Class C (X-17, s = 0.82), Class A (X-1.1, s 0.54), and Class B (X = 0.9, s = 0.22).Explanation / Answer
In the first question, the means and standard deviations of the groups are given. There are 2 independent variables, relationship status and sex while the dependent variable is income. This is the case for 2 way ANOVA, where we want to test if both the independent variables affect the outcome significantly.
In the second question, the proportions are given. The test for this would be a simple z-test for proportions.
For the third question, the dependent variable is the number of accidents and the independent variable is the type of licence. This is a case for 1 way ANOVA since there are 3 types of licences and we want to test if the means are significantly different from each other or not.
