1 Gun Ownershi and Gun-Related Mortali 15 marks The regulation of gun ownership is a highly contentious issue in many countries. Advocates of gun control argue that reduced rates of ownership will reduce violence, while opponents argue that gun ownership can protect individuals from violent crime. The le guns.xls has data on (r) gun ownership rates (guns per 100 people), (ii) homicide rates (deaths per 100,000) and (m) suicide rates (deaths per 100,000) taken across a sample of countries. Your task is to analyse these data to draw some useful conclusions about the statistical links between ownership and gunrelated mortality. Note that the way data is gathered and reported differs from country to country, so take your conclusions with a grain of salt. I Produce some histograms showing the distributions of all three variables and discuss your results. What key features of the data are shared by all three variables? I Produce some descriptive statistics (mean, median, standard deviation, skewness IQR) for each variable. Comment upon the results. I Do suicide rates have Inore intercountry variability than homicide rates? Produce measures of variability relative to the respective sample Ineans to perform this co1nparison. \\What do your results say about the relative nature of these variables? I Obtain scatter plots of both homicide and suicide rates against gun ownership rates. Do the variables appear to be related.D Discuss. I Estimate regression equations using the mortality rate [markers as the dependent variables and report your results. Test the hypotheses that gun ownership rates are unrelated to mortality rates at 50/0 signicance, giving the null and alternative hypotheses, a testatistic, critical value, pegfaluue and a conclusion. I Based upon your analysis, discuss the relationships you have found and outline some recommendations you would make to politicians or public health ofcials.
