Question: Taking stock An investor with a stock portfolio worth several hundred thousand dollars sued his broker due to the low returns he got from the portfolio at a time when the stock market did well overall. The investor's lawyer wants to compare the broker's performance against the market as a whole. He collects data on the broker's returns for a random sample of 36 weeks. Over the 10-year period that the broker has managed portfolios, stocks in the Standard & Poor's 500 index gained an average of 0.95% per week. The Minitab output below displays the results of a significance test.
(a) Do these data give convincing evidence to support the lawyer's case? Justify your answer.
(b) Interpret the P-value in context.
