This project analyzes the correlation between cigarette consumption and cancer mortality rates in lung, bladder, and kidney cancers. Using statistical tools and Excel, we examine the relationship between the number of cigarettes smoked per capita and the resulting death rates, focusing on R² values and regression analysis. We find that an increase in cigarette consumption correlates with a rise in lung cancer deaths, emphasizing the health hazards of smoking. Our findings suggest that public health measures like advertising and taxes could help reduce smoking intensity and, consequently, cancer rates.

b. Cigarettes smoked per Capita is significant, Prob. 7/10,000 happen by chance Regression is significant Eventhough R2 = 0.50, Other unspecified factors Ar work a. Coefficent 0.00445, if cigarettes smoked goes up by one per capita, death rate per 100,000 goes up by 0.004453
If cigarettes smoked per capita goes up by about 1%, i.e. by 25, then death rates for lung cancer go up by 25*0.0044 = 0.11125 per 100, 000 or deaths per year increase by 11,125 Or 0.11125/ 19.653, or about 0.6%. Called calculating elasticities at means

Economic and Health Significance • Smoking is hazardous to your health, especially for lung, bladder and Kidney cancer • Intensity of smoking, e.g cigarettes smoked per dollar of income and income per capita affect lung cancer death rates • Smoking intensity may be reduced by advertising health hazards and by imposing an excise tax • Development, as measured by income per capita may create dangerous toxins that cause lung cancer, e.g. acid rain from coal smoke stacks, particlates in the air, smog etc.
