Question:

US Obesity Levels by State and over Time These questions refer to the graphs found at http://stateofobesity.org/adult-obesity/ which show a sequence of maps of US states, colored by the proportion of the adult population classified as obese, for many different years between 1990 and 2014. Three of the maps, from 1990, 2000, and 2010, as well as a key for the color coding of percent obese, are shown in Figure 2.92.

(a) The cases are US states and one variable is year. Another variable is percent obese in that state, which could be a quantitative variable but here is classified into categories, making it a categorical variable. Using the legend given in Figure 2.92 (and ignoring the category of "No Data"), how many different categories are shown? (There is one more category already in the online graphs as this book goes to print and maybe another one by the time you are reading this!)

(b) Using Figure 2.92, what appears to be the highest category needed for any state in 1990? In 2000? In $2010 ?$
