Question

The Excel scatterplot shown on the previous page indicates that the annual revenues have an increasing trend. Therefore, linear, exponential, quadratic and cubic models were used to fit the trend, and the following relevant information became available after applying linear regression. What is the linear trend equation? a) y_ = 642.792t + 60.496 b). y_ = 642.792 + 60.496t c). y_ = 642.792 + 60.496t^2 d). y = 642.792 + 60.496t + c Using the linear trend equation, one can say that the predicted revenue increases by a). $642, 792, 000 a year. b) $604, 960, 000 z year. c). $60, 496, 000 a year. d) $6, 049, 600 a year. What is an exponential trend equation? a) y_t = exp(6.632 + 045t + [(.069)^2/2]) b). y_t = 6.632 + 045t + (.069/2) c). y_t = exp(6.632 + 045t + (.069/2)) d). y_t = 6.632 + 045t + [(.069)^2.2] What is a revenue forecast for 2012 found by the exponential trend equation? a). About 2 billion and 334 million dollars b). About 2 billion and 189 million dollars c). About 2 billion and 149 million dollars d). About 2 billion and 48 million dollars When three polynomial trend equations are compared, which of them provides the best fit? a). linear b). exponential c). quadratic d). cubic What is a revenue forecast for 2012 found by the polynomial trend equation with the best fit? a). About 2 billion and 149 million dollars b). About 2 billion and 174 million dollars c). About 2 billion and 334 million dollars d). About 2 billion and 48 million dollars
