How Does Cigarette Consumption Relate to Heart Disease Deaths?

Click For Summary

Discussion Overview

The discussion revolves around the relationship between cigarette consumption and deaths from coronary heart disease, focusing on data analysis and statistical interpretation. Participants are exploring how to analyze the provided data, including calculating the coefficient of determination and making predictions based on a linear model.

Discussion Character

  • Homework-related, Mathematical reasoning

Main Points Raised

  • One participant expresses confusion about how to analyze the data, specifically regarding the coefficient of determination and its implications for the relationship between cigarette consumption and heart disease deaths.
  • Another participant indicates they have resolved their confusion but does not provide details.
  • A request is made for the participant who resolved their confusion to share their solution for the benefit of others.
  • A participant confirms they calculated the coefficient of determination as 0.607.

Areas of Agreement / Disagreement

The discussion does not show clear consensus, as some participants have resolved their questions while others are still seeking clarification. There are no competing views presented, but the level of understanding varies among participants.

Contextual Notes

Participants have not explicitly detailed their assumptions or the methods used to arrive at their calculations, leaving some steps and interpretations unresolved.

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)
259.9
211.6
238.1
211.6
238.1
211.8
194.1
187.3
110.5
233.1
150.3
124.7
182.1
118.1
31.9
114.3
126.9
43.9
136.3

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.
