Where do students go to school? Although 81.4% of first time first-year students attended college in the state in which they lived, this percent varied considerably over the states. Here is a stemplot of the percent of first-year students in each of the 50 states who were from the state where they enrolled. The stems are 10s and the leaves are 1s. The stems have been split in the plot. The midpoint of this distribution is .3 64 4455 5 5 96 0 2 3 36 8 9 97 0 3 3 47 5 6 6 6 7 9 98 0 0 0 0 1 1 1 1 1 2 2 3 3 3 3 3 4 4 4 4 8 5 5 69 1 1 2 2 2
