A student intern took the information and built a regression model to predict game attendance for the upcoming season. The model should
A) accurately predict game attendance.
B) NOT predict game attendance accurately because the variable levels of today (i.e., population, Dow, etc.) are out of range of those used to build the regression model.
C) predict game attendance accurately because the variable levels of today (i.e., population, Dow, etc.) are out of range of those used to build the regression model.
D) predict game attendance accurately because the variable levels (i.e., population, Dow, etc.) are within range of those used to build the regression model.
