Question

A) With Time Period as the independent variable, the equation of the regression line is:
    a. y = 0.31 + 1.20x
    b. y = 0.79 + 3.47x
    c. y = 1.20 + 0.31x
    d. y = 3.47 + 0.79x


B) With Time Period as the independent variable, the carpet sales forecast for Month 11 is:
    a. 7,400 yards
    b. 12,160 yards
    c. 24,310 yards
    d. 38,960 yards


C) With Monthly Construction Permits as the independent variable, the equation of the regression line is:
    a. y = 0.31 + 1.20x
    b. y = 0.79 + 3.47x
    c. y = 1.20 + 0.31x
    d. y = 3.47 + 0.79x

LINEAR REGRESSION FORECASTING
Carpet World wants to develop a means to forecast its carpet sales. The store
manager would like to confirm which of two possible variables – time period vs.
monthly house construction permits - is a better indicator of carpet sales. The
manager has gathered data from city records of monthly house construction
permits and from store records on monthly sales. The data are as follows. Do the
necessary computations (express your results up to 2 decimal places) and choose
the best answer that would complete each statement.
