Question 3 5 pts The data are the weights of backpacks with books in them. You sample five students. The weights (in pounds) of their backpacks are 6.2, 7, 6.8, 9.1, and 4.3. What type of data is this? The type of data is mean O The type of data is average. The type of data is quantitative (numerical). The type of data is historical. The type of data is categorical (qualitative). Question 4 5 pts Does a low-calorie meal pay off? Some dieters say that eating less at just one meal is ineffective, because people compensate by eating more at other meals, but a new study contradicts that argument. Below is an excerpt from a NY Times article on this study: "For two weeks, researchers had 17 men and women eat all their meals and snacks, as much as they wanted, at a buffet where the exact quantities consumed could be weighed and caloric intake calculated. Then for the next two weeks, the participants ate a 200-calorie lunch, a commercially available food like a Kashi bar or a Lean Pocket. But the rest of the day, they ate whatever they wanted from the buffet. Not counting lunch, the participants consumed 1,568 calories on days they had the 200- calorie lunch and 1,560 on days when they did not - an insignificant difference. But overall, they consumed 245 fewer calories on low-calorie lunch days. The result of that - unsurprisingly - was weight loss: an average of 1.1 pounds per participant in two weeks." What type of study is this? This type of study is an experiment. This type of study is observational. This type of study is a standard deviation. This type of study is a report. This type of study is a focus. Question 5 Which types of displays work best for quantitative (numerical) variables? Cartesian graphs work best for quantitative (numerical) variables. Bar graphs, pie graphs, and pareto charts work best for quantitative (numerical) variables. None of the graphs listed work best for quantitative (numerical) variables. All of the graphs listed work best for quantitative (numerical) variables. Dotplots, histograms, and boxplots work best for quantitative (numerical) variables. 5 pts Question 3 5 pts The data are the weights of backpacks with books in them. You sample five students.
