QUESTION:

Below is a stemplot of the percent of residents aged 25 to 34 in each of the 50 states. As in the stemplot for older residents (page 33), the stems are whole percents, and the leaves are tenths of a percent. This time, each stem has been split in two, with values having leaves 0 through 4 placed on one stem, and values ending in 5 through 9 placed on another stem.

\(\begin{array}{l|l} 11 & 44 \\ 11 & 66778 \\ 12 & 0134 \\ 12 & 666778888 \\ 13 & 0000001111444 \\ 13 & 7788999 \\ 14 & 0044 \\ 14 & 567 \\ 15 & 11 \\ 15 & \\ 16 & 0 \end{array}\)

(a) Why did we split stems?

(b) Give an appropriate key for this stemplot.

(c) Describe the shape, center, and spread of the distribution. Are there any outliers?
