Given the following data, use least-squares regression to derive a trend equation: Period 2 3 4 5 6 Demand 6 9 8 11 12 11 The least-squares regression equation that shows the best relationship between demand and period is (round your responses to two decimal places): y = where y = Demand and x = Period What is your estimate of the demand in period 7? Estimated demand in period 7 is (round your response to two decimal places). What is your estimate of the demand in period 12? Estimated demand in period 12 is|(round your response to two decimal places)
