Two Sample Hypothesis Test that Will Be Used and Rationale for Using It: The twosamg hypothesis test is used to determine whether the level of income impacts the family size. State the Random Variable and Parameters in Words: In this m hypothesis test analysis, both g income variable and family size variable will be used to determine if income does affect family size. There will be two groups that the income categories will be distributed into. For group one, the household income ranges from 93000 to 103000. For group two, the household income ranges from 104000 to 115000. State Null and Alternative Hypotheses and Level of Signicance: The Null Hypothesis: There is no signicant difference between family size in group one and group 2's household. For two tailed (at): There is a signicant difference between family size in group one and group twos household. For one tailed (>): Group one has a statistically higher family size than group two. For one tailed (
