Question: I. (Dataset: states; variables "cigarettes" and "cig_tax_3")
Report all appropriate descriptive statistics (such as the mean, median, mode, and standard deviation) for variables:
"cigarettes" (bimonthly cigarette consumption across the U.S. states)
"cig_tax_3" (coded as 1, if the tax is $.07-$.64; 2 -- $.69-$1.36; and 3 - above $1.41)
II. (Dataset: states; variables "cigarettes" and "cig_tax_3")
Answer the following question: does cigarette consumption vary across the states with different cigarette tax?
Should you use crosstabulation or comparison of the means? Explain.
Report and interpret the results of the test.
III. (Dataset: states; variables "gay_support3" [1-low support; 2- mid-level; 3 - high support] and "secularism3" [1-religious; 2 - middle; 3 - secular])
A pundit suggests that aggregate support for gay rights depends on the level of religiosity across the states? Test this proposition.
Should you use crosstabulation or comparison of the means? Explain.
Report and interpret the results of the test.
IV. (Dataset: states; variables "carfatal" [number of motor vehicle fatalities per 100,000 residents] and "south" [coded as 1 if a state is southern; otherwise - 0])
An expert observes that, due to better climate conditions, the number of car fatalities is lower in southern states, compared to the rest of the U.S.A. Test this proposition.
Should you use crosstabulation or comparison of the means? Explain.
Report and interpret the results of the test.
