variables for the city of Albany: the number of
automobiles registered, the sales of alcoholic beverages, and the rainfall in inches.
How can this employee realistically predict the accidents in Albany for next year?
O Use the ratio of accidents versus each of the other variables and then average the
three values
O Use a multiple regression equation using accident as the dependent variable and
others as independent variables
O Use a multiple regression equation using automobiles registered as the dependent
variable and others as independent
variables
, O Use the sales of alcoholic beverages because the other variables are less significant
- Answers - Use a multiple regression equation using accident as the dependent
variable and others as independent variables.
cuz accidents the question, are the dependent variable the reason why is because rain,

7 Y-hat=a+b1X1 +b2X2
The constant is 3, the bl coefficient is 4, the b2 coefficient is —1, X1 is 3, and X2 is 6
What is the predicted value of Y?
O 15
O9
O 11
O 13
O 8 - Answers - 9
cuz 3+(4x3)+(-1x6)=9
8 Y-hat=a+b1X1 +b2X2+b3X3+b4X4
The constant is —8, the b1 coefficient is 14, the b2 coefficient is 20, the b3 coefficient is
—18, the b4 coefficient is —9, x1 is 1, x2 is 3, and x4 is 4.
What is the predicted value of Y?
