Develop an estimated regression equation using trade price and speed of execution to predict overall satisfaction with the broker. Let x 1 represent satisfaction with Trade Price. Let x 2 represent satisfaction with speed of execution. If required, round your answers to four decimal places. For subtractive or negative numbers use a minus sign even if there is a + sign before the blank. (Example: -300) = -0.6633 + 0.7746 x 1 + 0.4897 x 2 What is the coefficient of determination? If required, round your answers to four decimal places. 0.7256 Interpret the coefficient of determination. If required, round your answer to one decimal places. The regression model explains approximately 72.56 % of the variation in the values of overall satisfaction in the sample. (b) Use the t test to determine the significance of each independent variable. What are your conclusions at the 0.05 level of significance? We cannot conclude that 1 = 0. That is, there is a relationship between satisfaction with trade price and overall satisfaction with the electronic trade. We cannot conclude that 2 = 0. That is, there is a relationship between satisfaction with speed of execution and overall satisfaction with the electronic made
