Is global warming real (statistically significant)? If so:
is it due to greenhouse gases?
Is human activity a significant contributor?
Is it a good thing or a bad thing?
|Statistics in the news:
CDC reports this is also strongly related to education.
Some people are arguing that cigarette taxes are unfair as they put a disproportionate burden on the poor who use more cigarettes and have less money to go to college.
Average price per pack is about $3.81 or (rough estimate) about $2.50 if bought by the carton. average consumption is probably at least a pack per day (88% of smokers smoke every day, some 2 packs a day) for close to $1000 per year.
year 2000 Census Poverty thresholds were used in the CDC study. Poverty Threshold varies depending on family size from one individual ($8795), two persons ($11239) to up to about $35 K for families of 9 or more. http://www.census.gov/hhes/www/poverty/threshld/thresh00.html
It seems if we are talking per person, the right number is someplace
around $10K --all cash income from earnings, welfare, etc., before taxes.
So about 1/3 of people with incomes below $10K are spending about 10% of their resources on cigarettes. This would get a lot more pronounced if we had a family of smokers.
Does lack of education cause people to smoke, or does the expense of smoking keep people from getting an education?
Raw data on health habits is available from the National Health Interview
Survey with about 45,000 records. could be useful for courses.
