The American Association of Individual Investors (AAII) Online Discount Broker Survey gathers insights from members regarding their experiences with discount brokers. Participants in the survey were asked to evaluate both the speed of execution with their broker and their overall satisfaction with electronic trades. The potential responses (scores) included: no opinion (0), unsatisfied (1), somewhat satisfied (2), satisfied (3), and very satisfied (4). Each broker's scores were computed using a weighted average of individual respondent scores. Below are the summarized results from the survey:| Brokerage | Speed | Satisfaction ||-------------------------------|-------|--------------|| Scottrade, Inc. | 3.4 | 3.5 || Charles Schwab | 3.3 | 3.4 || Fidelity Brokerage Services | 3.4 | 3.9 || TD Ameritrade | 3.6 | 3.7 || E*Trade Financial | 3.2 | 2.9 || Vanguard Brokerage Services | 3.8 | 2.8 || USAA Brokerage Services | 3.8 | 3.6 || Thinkorswim | 2.6 | 2.6 || Wells Fargo Investments | 2.7 | 2.3 || Interactive Brokers | 4.0 | 4.0 || Zecco.com | 2.5 | 2.5 |Interactive Brokers received the highest scores for both speed and satisfaction, each attaining a perfect score of 4.0. In contrast, Zecco.com had the lowest scores in both categories, each at 2.5. This table provides valuable insights into customer perceptions of speed and satisfaction for each brokerage. **Transcription:**(e) Suppose Thinkorswim 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 2.6 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? (Round your answer to one decimal place.)[Text box for answer]

Based on market sales figures, approximately 7.9% of car owners in California own an electric or plug-in hybrid vehicle (EV). A marketing director at a local car dealership would like to know if their sales of EV's is any greater than what the state's sales proportions are. To examine this, they look over the last 500 sales (which they consider to be a representative sample of all car sales) and determine that 10.4% of those were EV sales. Is this statistically significant evidence that the dealership sells a higher proportion of EV's than the overall state's proportion? Which of the following are the correct null and alternative hypotheses for the hypothesis test used to determine significance? Ho:p = 0.079 Haip > 0.079 %3D O Ho:p = 0.079 Hai p > 0.104 O Ho:p 0.079 O Ho:p 0.104
