Determine the estimated regression equation that can be used to predict the overall score given the scores for Itineraries/Schedule, Shore Excursions, and Food/Dining. (Let x1 represent Itineraries/Schedule, x2 represent Shore Excursion, x3 represent Food/Dining, and y represent Overall score.

A congressperson wants to come up with a single value to describe the prices of homes in their district. However, their district consists of a few homes that are extremely expensive compared to the others. Which descriptive statistic should they use? a. Range b. Mode c. Median d. Mean

The Census Bureau Web site gives several choices for "average income" in its historical income data. In 2006, the median income of American households was $48,201. The mean household income was $66,570. The median income of families was $58,407, and the mean family income was $77,315. The Census Bureau says, “Households consist of all people who occupy a housing unit. The term ‘family’ refers to a group of two or more people related by birth, marriage, or adoption who reside together.”   Identify the reason for mean incomes for households being higher than median incomes for households.

The Condé Nast Traveler Gold List provides ratings for the top 20 small cruise ships. The data shown below are the scores each ship received based upon the results from Condé Nast Traveler's Annual Readers' Choice Survey. Each score represents the percentage of respondents who rated a ship as excellent or very good on several criteria, including Shore Excursions and Food/Dining. An overall score was also reported and used to rank the ships. The highest ranked ship, the Seabourn Odyssey, has an overall score of 94.4, the highest component of which is 97.8 for Food/Dining.
