The table below shows the shipments (in millions of dollars) of consumer durables and nondurables in Canada. Is there a linear relationship between the shipments of durables and nondurables? In other words, if we know the value of nondurables shipped in any one year, can we predict the value of durables during that year? (Hint: Make the value of nondurables the independent variable.) According to the model, if at any given year the nondurables shipment is $200,000 million, what would the predicted amount for durables shipment be for the same year? Construct a confidence interval for the average y value for $200,000 million. Use the statistic to test to determine whether the slope is significantly different from zero. Use a = 0.05.
