There is much current debate about global warming and what we might do to reduce our "carbon footprint". Canada has been widely criticized for its record in terms of contributing to this problem. In general, it is suggested that the wealthiest countries in the world tend to emit the largest proportion of all CO2 emissions. In the data below, we have listed the household ID # and CO2 emissions (tonnes) documented for 15 different Canadian households. Household CO2 emissions (tonnes/year) ID# 8 14 16 12 15 13 15 14 15 8 13 12 14 15 la. With this small group of 15 households, provide the mean level of CO emissions per household and the appropriate "measure of dispersion" for this same variable (10 marks) 1b. Which household "deviates most from the mean" in terms of CO2 emissions (2 marks)? 1c. What is the range of this distribution? (2 marks) 1d. What is the median on CO2 emissions? Which Household ranks worst and which ranks the best? (5 points) le. Let us assume that the full population of households in Canada have the same "mean" and "standard deviation" as calculated above. Let us also assume that the distribution of CO2 emissions across Canadian households is normally distributed. On this basis: 1f. What proportion of households produced less than 7 tonnes of CO2? (5 marks) 1g. What percentage of households produced between 7 tonnes and the mean on this variable? (5 marks)Problem 5. The following are the results from a recent poll of Canadians on their smoking behavior. A total sample of 1300 Canadians were interviewed. This included 150 persons interviewed in Atlantic Canada, 300 in Quebec, 300 in Ontario, 250 in the Prairie provinces and 300 in BC. NOTE: The sample sizes in this poll are typical of our national polls in Canada. Smoking Behavior Canada Atlantic Canada Quebec Ontario Prairies B.C. Smoker 252 39 63 57 48 45 Non-Smoker 1048 111 237 243 202 255 Total sample 1300 150 300 300 250 300 Working with this sample, all of your calculations below must involve "confidence intervals". In so doing, follow the convention of setting alpha at .05 with all calculations. 5a. What proportion of Canadians are smokers? (5 marks) 5b. What proportion of Atlantic Canadians smoke (note: sample size is only 150 here)? What about Quebecers (n=300)? What about Ontario (n=300)? The Prairies (n=250)? BC (n=300)? (10 marks) 5c. Let's assume the Headline in the Toronto Sun in summarizing this poll states: "Quebecers are much more likely to smoke than Ontario residents" Critique this headlineStep by Step Solution
