Use the data and this chart to answer the questions below. Because the data are categorized by quarter, the forecast may need to account for seasonal impacts. Use the multiple regression model defined below to forecast PepsiCo's revenues. 1. A colleague has suggested the presence of a trend in PepsiCo’s revenues, disregarding seasonal impacts. Use the regression equations identified below to forecast using only trend. (a) Using a second-order model, develop a nonlinear estimated regression equation [T = bo + bit + bzť²] to forecast PepsiCo's revenues. Use the nonlinear equation to forecast revenues for each quarter of 2021. Using a= 0.05, discuss the significance (R-square, F-test and t-tests) of the equation in part (d). (b) Do you prefer the estimated regression equation developed in part (b) or part (d)? Explain. (c)
