Suppose we have the following variables:

Y: dependent quantitative variable

X: independent variable; quantitative variable.

Location: independent variable; categorical variable. Values are either North, South, East, West

Suppose we create the multiple linear regression model whose independent variables are X and the dummy variables associated with the variable Location. We receive the following coefficients table in the model output:

Variable	Estimate of coefficient	p-value
(intercept)	500	Less than 0.0001
X	5	Less than 0.0001
Location North	59	Less than 0.0001
Location East	28	Less than 0.0001
Location West	170	Less than 0.0001

1. Calculate the predicted value of Y in the West when X = 19

2. Calculate the predicted value of Y in Segment A when X = 19
