(b) Write down the theoretical model [i.e. the population model) that would be appropriate to describe the linear relationship between the price and the number of pieces in a Lego set. Use price as the response variable and pieces as the explanatory variable. Be sure to use the correct notation. (c) Provide an interpretation for the population intercept for this example. In your interpretation consider what is part of a Lego set before the pieces are added. (d) Provide an interpretation for the population slope for this example
