A brokerage firm wants to see whether the type of account a customer has (Silver, Gold, Platinum) affects the type of trades that a customer makes (in person, by phone, or on the Internet). It collects a random sample of trades made for its customers over the past year and performs a test. . Melissa Kemmerle. October 19, 2012. Goals. Review regression and measures of fit.

Ricardo Casullo, president of CFS, has been contacted by Nike Inc. to forecast exchange rates for the next five years. Ricardo Casullo assigned to the project Mr. Walter Ritz, Vice President of CFS and manager of the Forecasting Department. Mr. Ritz is an expert on currency forecast who is often quoted in the financial press and who is a regular on CNBC’s Power Lunch. Mr. Ritz first task was to review several of Nike's annual reports and industry reports. . 3. Plans.
