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 chemistry experiment is performed measuring the solubility of potassium chloride (KCl) in water at different temperatures. The goal was to determine if there is a linear relationship between the temperature of the water and how much KCl can dissolve, measured as grams per 100 milliliter (g/100mL).
After the experiments were performed, the following data was collected with temperature being the independent x-variable and solubility being the dependent y-variable:

Based on the data given for temperature and solubility of KCl and without doing any math yet, which of the following do you predict would best describe the relationship between these variables?
A positive linear relationship (r close to 1)
A positive linear relationship (r close to -1)
A negative linear relationship (r close to 1)

Write a model equation that includes indicator vari-ables to incorporate intake setting, and interpret each of the b coefficients.
b. What additional predictors would be needed to in-corporate interaction between temperature and in-take setting?
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.
