"Reject Ho; there is sufficient evidence to conclude that μ1 – μ2 > 0. There is sufficient evidence to support the claim that unfiltered king size cigarettes have a mean tar content greater than that of filtered 100 mm cigarettes. The results suggest that filters are effective in reducing the tar content in cigarettes. "

Do not reject Ho; there is not sufficient evidence to conclude that μ₁–μ₂≠0. There is not sufficient evidence to support the claim that menthol cigarettes and non-menthol cigarettes have different amounts of nicotine. No; menthol does not appear to have an effect on the nicotine content.

Question 1
Go to the list of datasets located on the website http://wps.aw.com/aw_stock_ie_3/178/45691/11696965.cw/index.html . Right-click the one named “Guns Data (Stata dataset)”, save it somewhere you can access it and then open it in Stata. This dataset contains panel data from 50 states plus the District of Columbia for the years 1977 through 1999. A detailed description is given in the ﬁle “Guns Data Description (PDF)” on the same page. We are interested in the eﬀects of “shall-issue” laws relating to concealed handguns. The variable “shall” is 1 if a state has such a law, 0 otherwise. States that have “shall-issue” laws *shall* (i.e., must) give a concealed gun permit to anyone that wants one (and isn’t a felon, mentally incompetent). States that do not have “shall-issue” laws may issue permits, but generally do so only to certain types of people (i.e., their laws are much stricter). Proponents of “shall-issue” laws argue that they will reduce crime, because criminals will be deterred by the knowledge that some people are carrying guns. Critics argue that “more guns means more crime”. 1. The outcome we will analyze is the log of violence (i.e., you need to create a variable such as ln_vio using a command such as “gen lnvio=ln(vio)”. Why is it convenient to use the log of violence as the outcome variable (rather than the number of violent incidents as recorded by “vio”)? [2 points] 2. Estimate a regression of...
