The American Association of Individual Investors (AAII) On-Line Discount Broker Survey polls members on their experiences with discount brokers. As part of the survey,
members were asked to rate the quality of the speed of execution with their broker as well as provide an overall satisfaction rating for electronic trades. 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
calculating a weighted average of the scores provided by each respondent. A portion of the survey results follow (AAII website, February 7, 2012).

A
b. What does the scatter diagram developed in part (a) indicate about the relationship between the two variables?
The scatter diagram indicates a positive
linear relationship between x = speed of execution rating and y = overall satisfaction rating for electronic
trades.
c. Develop the least squares estimated regression equation. Enter negative value as negative number.
Satisfaction =
0.9206 +
0.7199 Speed (to 4 decimals)
d. Provide an interpretation for the slope of the estimated regression equation.
The slope of the estimated regression line is approximately
0.7199 (to 4 decimals). So, a one unit increase
v in the speed of execution rating will
increase the overall satisfaction rating by approximately
0.7 points (to 1 decimal).
e. Suppose Fidelity Brokerage Services developed new software to increase their speed of execution rating. If the new software is able to increase their speed of
execution rating from the current value of 2.5 to the average speed of execution rating for the other 10 brokerage firms that were surveyed, what value would you
predict for the overall satisfaction rating?
(to 3 decimals)

Recently airlines have cut services, such as meals and snacks during flights, and started charging extra for some services, such as accommodating overweight luggage, last-minute flight changes, and pets traveling in the cabin. However, they are still concerned about service. Recently, a group of four carriers hired Brunner Marketing Research Inc. to survey passengers regarding their level of satisfaction with a recent flight. The survey included questions on ticketing, boarding, in-flight service, baggage handling, pilot communication, and so forth. Twenty-five questions offered a range of possible answers: excellent, good, fair, or poor. A response of excellent was given a score of 4, good a 3, fair a 2, and poor a 1. These responses were then totaled, so the total score was an indication of the satisfaction with the flight. The greater the score, the higher the level of satisfaction with the service. The highest possible score was 100. Brunner randomly selected and surveyed…
