Consider the following model for baseball game attendance. Attendance is measured in hundreds and is the dependent variable. Bad weather is a dummy variable that is 1 if its stormy on the day. Price measures the ticket price in dollars and temperature in degrees Fahrenheit. Attendance = 25 - 14*Bad Weather - 0.15*price - 0.3*temperature How would you interpret the coefficient on Bad weather? O All else equal, on average if a baseball game occurs when it is stormy, then there will be 1,400 fewer attendees than there would be otherwise.
