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. The data file (broker) is enclosed. a. Find the correlation coefficients between overall satisfaction and trade price as well as overall satisfaction and speed of execution. Which between speed or trade price would be more suitable to use to predict overall satisfaction? b. Run a regression to predict overall satisfaction based on trade price. Give your equation. c. Use your equation to estimate overall satisfaction when trade price is 2.9. The following is the output of a multiple regression analysis to predict overall satisfaction with the broker
