MHB How Does Cigarette Consumption Relate to Heart Disease Deaths?

AI Thread Summary
Cigarette consumption is analyzed in relation to coronary heart disease deaths across various countries, with the United States leading in per capita consumption at 3,350 cigarettes. The coefficient of determination calculated at 0.607 suggests a moderate positive correlation between cigarette consumption and heart disease mortality rates. A prediction model using the linear equation ax + b is proposed to estimate deaths per 100,000 for a country with a per capita consumption of 2,000 cigarettes. The discussion highlights the importance of statistical analysis in understanding health risks associated with smoking. Overall, the data indicates a significant relationship between cigarette use and heart disease fatalities.

I just need a little assistance on the last two questions. I place per capita and death in L1 and L2 but I am lost.

Country Per Capita Cigarette Consumption
3900
United States 3350
Canada 3220
Australia 3220
New Zealand 2790
United Kingdom 2770
Ireland 2290
Finland 2160
West Germany 1890
Netherlands 1810
Austria 1770
Belgium 1700
Mexico 1680
Italy 1510
Sweden 1270
Spain 1200
Norway 1090

Deaths from Coronary Heart Disease (per 100,000)

3. What does the coefficient of determination indicate about the relationship?
Would the coefficient of 0.607 indicate there's a link between the variables?4. Use the data above to predict the number of death (per 100,000) in a country with a per capita consumption of cigarettes of 2000.

Would the ax+b equation be useful here?

Sorry, I know this one is a little long.

Would you mind posting your solution for the benefit of the community?
 
Sure! I got 0.607.
 

Thread 'Trigonometry problem of interest'

Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
