Construct a stem-and-leaf plot of the pulse rates. b. Construct a boxplot of the pulse rates. c. Describe the shape of the distribution of the pulse rates. d. The boxplot provides information about the distribution of pulse rates for what population? 3.35 Consumer Reports in its May 1998 issue provides cost per daily feeding for 28 brands of dry dog food and 23 brands of canned dog food. Using the Minitab computer program, the following side-by-side boxplot for these data was created. DOG FOOD COSTS BY TYPE OF FOOD 3.5- 3.0- 2.5- 2.0- 1.5 1.0 .5 0 CAN DRY TYPE a. From these graphs, determine the median, lower quartile, and upper quartile for the daily costs of both dry and canned dog food. b. Comment on the similarities and differences in the distributions of daily costs for the two types of dog food. Summarizing Data from More Than One Variable: Graphs and Correlation
