A study monitored several thousand people over decades of cigarette usage and recorded the Incidence of lung cancer, described below, where X ls cigarette usage In packs smoked per day and Y is relative risk of cancer. The relative risk is dened as the incidence of lung cancer in the exposed group divided by the incidence of lung cancer in the unexposed group. Cig. packs/ day (X): 0 0.5 1 1.5 2 2.5 Relative risk (Y): 1 5 11 18 24 28 Summary statistics: 5 2 1.250, g 214.500, EtaEV 24.375, EtaE) (yig) 2 49.750, 2(yiy)2 2569.500 Calculate the values 30 and BI that describe the least-squares regression line relating cigarette usage and relative risk of lung cancer.

[1 pt(s) ] Submit Answer Tries 0/3 What does the correlation coefficient tell us about the relationship between cigarette usage and relative risk of lung cancer? There is a weak association between cigarette usage and lifetime risk of lung cancer. There is no association between cigarette usage and lifetime risk of lung cancer. There is a strong positive linear association between cigarette usage and lifetime risk of lung cancer. There is a strong negative linear association between cigarette usage and lifetime risk of lung cancer. [2 pt(s)] Submit Answer Tries 0/1
