(a) Develop an estimated regression equation using trade price and speed of execution to predict the overall satisfaction with the broker. (Round your numerical values to four decimal places.) $\hat{y}=$ Interpret the coefficient of determination. (Round your answer to two decimal places.) This regression model explains approximately $\%$ 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. Test whether the regression parameter ${?}_1$ is equal to zero. Find the $p$-value. (Round your answer to four decimal places.) $?$-value $=$ What is the conclusion for the test at the 0.05 level of significance? O We reject $H_0$. We can conclude that there is a relationship between satisfaction with trade price and overall satisfaction with the electronic trade. We reject $H_0$. We cannot conclude that there is a relationship between satisfaction with trade price and overall satisfaction with the electronic trade. We fail to reject $H_0$. We can conclude that there is a relationship between satisfaction with trade price and overall satisfaction with the electronic trade. We fail to reject $H_0$. We cannot conclude that there is a relationship between satisfaction with trade price and overall satisfaction with the electronic trade. Test whether the regression parameter ${?}_2$ is equal to zero. Find the $p$-value. (Round your answer to four decimal places.) $?$-value $=[$ What is the conclusion for the test at the 0.05 level of significance? We fail to reject $H_0$. We can conclude that there is a relationship between satisfaction with speed of execution and overall satisfaction with the electronic trade. ? We reject $H_0$. We can conclude that there is a relationship between satisfaction with speed of execution and overall satisfaction with the electronic trade. We reject $H_0$. We cannot conclude that there is a relationship between satisfaction with speed of execution and overall satisfaction with the electronic trade. We fail to reject $H_0$. We cannot conclude that there is a relationship between satisfaction with speed of execution and overall satisfaction with the electronic trade. (c) Interpret the estimated regression parameters. Are the relationships indicated by these estimates what you would expect? $\begin{array}{l}\text{ O Yes }\\ \text{ No }\end{array}$ these Derformance levels. (Round your answer to one decimal place.) (e) What concerns (if anv) do vou have with reaard to the possible resoonses the respondents could select on the survey?
