Question

Question 6 4 pts I decide to conduct a multiple regression analysis to predict the attendance at a major league baseball game. I use the size of the stadium as a quantitative independent variable and the type of game as a qualitative variable (with two levels day game or night game). My "best model" turns out to be the model: E ()-Bo11+B2*2 Where -size of the stadium T21 if a day game, 0 if a night game A plot of the y-x1 relationship would show: Two parallel lines Two non-parallel lines O Two non-parallel curves Two parallel curves

Explanation / Answer

when x2 = 1

y = b0 + b1x1 + b2

when

x2 = 0

y = b0 + b1 x1

hence

they are parallel lines

A) two parallel lines is correct
