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 ratetheir 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), somewhatsatisfied (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 thesurvey results follow. (Let x, represent satisfaction with trade price, x, represent satisfaction with speed of execution, and y represent overall satisfaction with electronic trades.)BrokerageSatisfaction with Trade PriceSatisfaction with Speed of ExecutionOverall Satisfaction with Electronic TradesBrokerage 13.33.53.4Brokerage 23.33.23.3Brokerage 33.03.53.9Brokerage 43.03.53.6Brokerage 52.83.12.8Brokerage 62.43.32.8Brokerage 72.53.92.9Brokerage 82.33.73.7Brokerage 92.72.52.5Brokerage 102.42.62.2Brokerage 113.64.04.0Brokerage 122.62.42.4Brokerage 133.13.14.0Brokerage 144.01.11.9(a) Develop an estimated regression equation using trade price and speed of execution to predict the overall satisfaction with the broker.
