A sample of adults was asked to indicate the amount of money, in dollars, they would be willing to spend on a wedding gift. When a histogram was constructed based on the responses given by each adult, most of the dollar amounts were on the larger side, with only a few dollar amounts on the smaller side. Two measures of center were calculated for this sample: $150 and $279. One of these measures is the mean, and the other is the median. Which measure must be the mean? The mean is $279 because the distribution of dollar amounts would be skewed to the left. The mean is $279 because the distribution of dollar amounts would be skewed to the right. The mean is $150 because the distribution of dollar amounts would be skewed to the left. The mean is $150 because the distribution of dollar amounts would be skewed to the right.

After giving a statistics exam, professor Dang determined the following five-number summary for her class results: 60 68 77 89 98. Use this information to draw a box plot of the exam scores

Suppose that a polling company surveyed 600 people about how much time they spend watching television each day. The results of this survey were compiled and used to create this relative frequency histogram.   Assume that all percentages shown in the histogram are whole numbers. Each of the bars in this histogram includes only the left endpoint of the class except for the last bar, which also includes the right endpoint. What percentage of respondents said that they watch television at least six hours per day? How many respondents said that they watch television between three and five hours per day?

A statistical program is recommended. 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. Shore Ship Overall Food/Dining Excursions Seabourn Odyssey 94.4 90.9 97.8 Seabourn Pride 93.0 84.2 96.7 National Geographic Endeavor 92.9 100.0 88.5 Seabourn Sojourn 91.3 94.8 97.1 Paul Gauguin 90.5 87.9 91.2 Seabourn Legend 90.3 82.1 98.8 Seabourn Spirit 90.2 86.3 92.0 Silver Explorer 89.9 92.6 88.9 Silver Spirit 89.4 85.9 90.8 Seven Seas Navigator 89.2 83.3 90.5 Silver Whisperer…
