Suppose we fit a regression line to predict the number of incidents of lung cancer per 10,000 people from the number of cigarettes smoked in a year. For a particular year, we predict the incidence of lung cancer to be 7.9 per 10,000 people, and the residual for this year is -0.42.
Did we overestimate or underestimate the incidence of lung cancer? Explain your reason
Homework Answers
since we know that residual value =actual value -estimated value
the residual value is negative here which indicate that estimate value is greater than actual value
therefore we overestimate the incidence of lung cancer

Lung Cancer & Smoking Case Study A causal relationship between cigarette smoking and lung cancer was first suspected in the 1920s on the basis of clinical observations. To test this apparent association, numerous epidemiologic studies were undertaken between 1930 and 1960. Two studies were conducted by Richard Doll and Austin Bradford Hill in Great Britain The first was a case-control study begun in 1947 comparing the smoking habits of lung cancer patients with the smoking habits of other patients. The...
