DATA (a) Develop an estimated regression equation using trade price and speed of execution to predict overall satisfaction with the broker. Let xi represent satisfaction with Trade Price. (a) Develop an estimated regression equation using trade price and speed of execution to predict overali satisfaction with the broker. Let x i represent satistaction whth Trade Price. Let x z represent sotisfoction wh speed execution. If requifed, round your answers to four decimal places. For subtractive or negative numbe use a minus sign even if there is a + sign before the blank. (Example: -300 ) What is the coefticient of determination? If required, round your arsenern to four decinal places. Iiserpret the coefficene of determinatson, If required, round vour anawer to one decimal places. The regreision model explaies approwimately Wo the variation in the values of overall satisfaction in the sample. (b) Uie the lest to determine the signicance of each independent varable.

Are the relationships indicated by these estimates what you would expect? (1) 0 is the estimated overall satisfaction with the electronic trade when satisfaction with trade price and speed of execution are both 0 . 1 is the estimated change in overali satisfaction with the eiectronic trade if satisfaction with trade price is heid constant and there is a 1 point increase in satisfaction with speed of execution. 2 is the estimated change in overall satisfaction with the electronic trade if satisfaction with speed of execution is held constant and there is a 1 point increase in satisfaction with trade price. (ii) 0 is the estimated overall satisfaction with the electronic trade when satisfaction with trade price and speed of execution are both 0 . t is the estimated change in overall satisfaction with the electronic trade if satisfaction with speed of execution is held constant and there is a 1 point increase in satisfaction with trade price. 2 is the is the estimated change in overall satisfaction with the electronic trade if satisfaction with trade price is held constant and there is a 1 point increase in satisfaction with speed of execution. (iii) 0 is the estimated overall satisfaction with the electronic trade when satisfaction with trade price and speed of execution are both 1 . t is the estimated change in overall satisfaction with the electronic trade if satisfaction with speed of execution is held constant and there is a 1 point increase in satisfaction with trade price. z is the is the estimated change in overall satisfaction with the electronic trade if satisfaction with trade price is held constant and there is a 1 point increase in satisfaction with speed of execution. (iv) 0 is the estimated overall satisfaction with the electronic trade when satisfaction with trade price and speed of execution are both 1 . 1 is the estimated change in overall satisfaction with the electronic trade if satisfaction with trade price is held constant and there is a 1 point increase in satisfaction with speed of execution. 2 is the estimated change in overall satisfaction with the electronic trade if satisfaction with speed of execution is held constant and there is a 1 point increase in satisfaction with trade price. (d) Finger Lakes Investments has developed a new electronic trading system and would like to predict overall customer satisfaction assuming they can provide satisfactory levels of service levels (3) for both trade price and speed of execution. Use the estimated regression equation developed in part (a) to predict overall satisfaction level for takes Investments if they can achieve these performance levels. If required, round your answer to one decimal places. Do not round intermediate calculations.
