3. [-/1 Points] DETAILS CAMMBA4 7.E.011.MI. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER You may need to use the appropriate technology to answer this question. An investors association's on-line discount broker survey polls members on their experiences with electronic trades handled by discount brokers. As part of the survey, members were asked to rate their satisfaction with the trade price and the speed of execution, as well as provide an overall satisfaction rating. Possible responses (scores) were no opinion (0), unsatisfied (1), somewhat satisfied (2), satisfied (3), and very satisfied (4). For each broker, summary scores were computed by computing a weighted average of the scores provided by each respondent. A portion of the survey results follow. (Let x, represent satisfaction with trade price, x, represent satisfaction with speed of execution, and y represent overall satisfaction with electronic trades.) Brokerage Satisfaction with Trade Price Satisfaction with Speed of Execution Overall Satisfaction with Electronic Trades Brokerage 1 3.3 3.5 3.4 Brokerage 2 3.3 3.4 3.5 Brokerage 3 3.2 3.5 3.9 Brokerage 4 2.8 3.7 3 .8 Brokerage 5 3.0 3 .3 3.0 Brokerage 6 2.4 3.3 2.6 Brokerage 7 2.5 3.7 2.9 Brokerage 8 2.5 3.9 3.5 Brokerage 9 2.5 2.7 2.5 Brokerage 10 2.2 2.6 2.4 Brokerage 11 3.6 4.0 4.0 Brokerage 12 2.4 2.6 2.4 Brokerage 13 3.1 2.9 4.0 Brokerage 14 4.0 1.1 2.1(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.) y: Interpret the coefcient 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 signicance of each independent variable. Test whether the regression parameter D1 is equal to zero. Find the pvalue. (Round your answer to four decimal places.) What is the conclusion for the test at the 0.05 level of significance? 0 We fail to reject HO' We cannot conclude that there is a relationship between satisfaction with trade price and overall satisfaction with the electronic trade. 0 We reject H0. We can conclude that there is a relationship between satisfaction with trade price and overall satisfaction with the electronic trade. 0 We fail to reject HO' We can conclude that there is a relationship between satisfaction with trade price and overall satisfaction with the electronic trade. 0 We reject \"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.) What is the conclusion for the test at the 0.05 level of significance? 0 We fail to reject H0" We can conclude that there is a relationship between satisfaction with speed of execution and overall satisfaction with the electronic trade. 0 We reject H0. We cannot conclude that there is a relationship between satisfaction with speed of execution and overall satisfaction with the electronic trade. 0 We reject H0" We can conclude that there is a relationship between satisfaction with speed of execution and overall satisfaction with the electronic trade. 0 We fail to reject H0. We cannot conclude that there is a relationship between satisfaction with speed of execution and overall satisfaction with the electronic trade. (d) An investment company has developed a new electronic trading system and would like to predict overall customer satisfaction assuming they can provide satisfactory service levels (3) for both trade price and speed of execution. Use the estimated regression equation developed in part (a) to predict the overall satisfaction level for the investment company if they can achieve these performance levels. (Round your answer to one decimal place.) (e) What concerns (if any) do you have with regard to the possible responses the respondents could select on the survey?
