Chapter 14.1, Problem 12E
A manufacturer of wood stoves collected data on y = Particulate matter concentration and x1 = Flue temperature for three different air intake settings (low, medium, and high).
- a. Write a model equation that includes indicator variables to incorporate intake setting, and interpret each of the β coefficients.
- b. What additional predictors would be needed to incorporate interaction between temperature and intake setting?

A study was conducted to see if a person's income will affect their well-being. We want to create a model with Y = well-being index, and X =
income in $1,000. The dependent variable in this study is:
Income in $1,000
Well-being index
Neither
Freshcrim specializes in the sales of ice cream from street trolleys in the centers of many cities. Some factorsthat may determine the sales of ice cream are: the atmospheric temperature, the location of the trolley, therain and the humidity. However, there exists a hypothesis that the sales of ice cream during the summer aresignificantly correlated only with atmospheric temperature. They defined two variables: X : the meanatmospheric temperature and Y : the sales. They considered the month of July of this year in a randomsample of 30 cities. For each city in the sample, let x be the mean temperature in degrees Fahrenheit and ythe mean sales per day in dollars per 100,000 residents. The data are given below. A regression model wasrun, with Y as the dependent variable and X as the independent variable.
