City government has collected the following data on annual sales tax collections and new car registrations:

a) The least-squares regression equation that shows the best relationship between sales tax (in millions) and car registrations (in thousands) is (round your responses to three decimal places and include a minus sign if necessary):

y = + x

where y = Dependent Variable and x = Independent Variable.

Part 3

b) Using the least-squares regression equation, the estimated sales tax collection when the new number of registrations total is 23,000 = million (round your response to two decimal places).

Part 4

c) The coefficient of correlation for the least-squares regression = (round your response to four decimal places).

Part 5

The coefficient of determination for the least-squares regression = (round your response to four decimal places).

a) The ! equation that shows the best relationship between sales tax (in millions) and car registrations (in thousands) is (round your responses to three decimal places and include a minus sign if necessary): y^=+x where y^= Dependent Variable and x= Independent Variable
