A test is conducted in eight cities to see if giving away free transit system maps will increase bus ridership. In a regression analysis, the dependent variable is the increase in bus ridership in thousands of persons from the start of the test until its conclusion. The independent variables are X1 = the number in thousands of free maps distributed and X2 = a binary equal to 1, if the city has free downtown parking and 0 otherwise. The estimated regression equation is Y = 1.32 .0345X1-1.45X2. ...**Weegy:** The estimated regression equation for Y should be Y = 1.32+.0345X1-1.45X2. There is error in your given equation.
