Worked Solution & Example Answer:The pie chart shows the results of an investigation into the tobacco-smoking habits of 20000 people in 2008 - Edexcel - GCSE Biology - Question 5 - 2017 - Paper 1
Step 1
Calculate the number of individuals who were daily smokers in 2008.
Answer
To find the number of daily smokers, we first note that 17% of the 20000 individuals were daily smokers. We can calculate this by using the formula:
ext{Number of Daily Smokers} = ext{Total Individuals} imes rac{ ext{Percentage of Daily Smokers}}{100}Substituting the values:
ext{Number of Daily Smokers} = 20000 imes rac{17}{100} = 3400Thus, the number of individuals who were daily smokers in 2008 is 3400.
Step 2
Suggest one reason why these people gave up smoking tobacco.
Answer
One reason why these individuals may have given up smoking tobacco could be increased awareness of the health risks associated with smoking. Educational campaigns highlighting the dangers of tobacco use may have contributed to a change in behavior, encouraging former smokers to quit.
