2022 Engineering Department StudentID:90205312 First/Last Kaan Demir Name: 008 Question 1: Examine the Lung Cancer Mortality Risk graph given below. The curves plotted are iso-risk contours (curves formed by points that belong to a fixed level of risk). The mortality Risk is expressed as number of deaths due to lung cancer per 100,000 people per year. Horizontal axis is the cigarette smoking Intensity expressed as cigarettes smoked per day. Vertical axis is Duration expressed as years since smoking habit has started. Duration (years) 80 70 10 60 20 10 200- 100 300 980- 950- 900- 850 800- 700 600. 500- 400 0 20 40 Intensity (cigarettes/day) 60 80 100 a) Determine the Risk from the graph when Intensity=55 and Duration=30. b) What is the Risk when Intensity=60 and Duration=20? For the same value of Duration=20 for what value of Intensity the Risk is halved (cut down by 50%)? c) What is the Risk when Intensity=40 and Duration= 5? Maintaining the same Intensity=40 for what value of Duration the Risk is doubled (increased by 100%)? d) For what values of Intensity and Duration the Risk=400 isocurve intersects the 1.Duration=3-Intensity line? Hint: expression a-Duration=-Intensity is an equation of a line which passes through the origin (Duration,Intensity)=(0,0). Risk= d.rt/yr ex: 450 Risk= d.rt/yr exc 500 Intensity= Risk= Duration: Intensity= Duration= cig/day ex: 40 d.rt/yr ex: 450 lyr ex: 25 cig/day ex: 50 yr ex: 23 2022 Engineering Department StudentID:90205312 First/Last Kaan Demir Name: 008 Question 1: Examine the Lung Cancer Mortality Risk graph given below.
