The goal of a nutritional study was to compare the caloric intake of adolescents living in rural areas of the US with the caloric intake of those living in urban areas. A random sample of ninth-grade students from one high school in a rural area was selected. Another random sample of ninth graders from one high school in an urban area was selected. Each student in the sample kept records of all the food he or she consumed in one day. The back to back stemplot displays the number of calories of food consumed per kilogram of body weight for each student on that day.
a. Write a few sentences comparing the distribution of the daily caloric intake of 9th-grade students in one rural high school with the distribution of the daily caloric intake of 9th-grade students in the urban high school.
b. Is it reasonable to generalize the findings of this study to all rural and urban 9th-grade students in the US?
