The percentage of teens not in school or working for the 50 states are shown in the following table. (Assume this is indicative of the high school dropout rate.) State Rate State Rate Alabama 12% Kansas 5% Alaska 10% Kentucky 11% Arizona 11% Louisiana 13% Arkansas 12% Maine 8% California 8% Maryland 9% Colorado 6% Massachusetts 4% Connecticut 6% Michigan 10% Delaware 8% Minnesota 5% Florida 11% Mississippi 14% Georgia 11% Missouri 9% Hawaii 11% Montana 9% Idaho 11% Nebraska 5% Illinois 9% Nevada 14% Indiana 7% New Hampshire 6% Iowa 5% New Jersey 7% New Mexico 11% South Dakota 9% New York 7% Tennessee 9%Indiana 7% New Hampshire 6% Iowa 5% New Jersey 7% New Mexico 11% South Dakota New York 7% Tennessee 90%% North Carolina 10% Texas 10% North Dakota 4% Utah 10% Ohio 8% Vermont 4% Oklahoma 9% Virginia 5% Oregon 9% Washington 7% Pennsylvania 6% West Virginia 15% Rhode Island 5% Wisconsin 6% South Carolina 8% Wyoming 9% Note that the percentages range from a low of 4% to a high of 15%. In constructing a stem-and-leaf display for these data, if we regard each percentage as a two-digit number and use the first digit for the stem, then there are only two possible stems, 0 and 1. One solution is to use repeated stems. Consider a scheme that divides the leaf range into five parts: 0 and 1, 2 and 3, 4 and 5, 6 and 7, and 8 and 9. Then, for example, stem 0 could be repeated as given below. 0 with leaves 0 and 1 Ot with leaves 2 and 3 of with leaves 4 and 5 Os with leaves 6 and 7 0* with leaves 8 and 9 Construct a stem-and-leaf display for this data set that uses stems Ot, Of, Os, 0*, and 1, it, and if. (Enter numbers from smallest to largest separated by spaces. Enter NONE for stems with no values.)O with leaves 0 and 1 0t with leaves 2 and 3 Of with leaves 4 and 5 05 with leaves 6 and 7 0* with leaves 8 and 9 Construct a stemand-leaf display for this data set that uses stems 0t, 01', 0s, 0*, and 1, 1t, and 1f.

A typical dropout rate is 5%. The dropout rates range from 5% to 12%. The stemleaf display shows that the distribution of high school dropout rates is slightly skewed to the right. A typical dropout rate is 9%. The dropout rates range from 4% to 15%. O The stemileaf display shows that the distribution of high school dropout rates is slightly skewed to the right. A typical dropout rate is 7%. The dropout rates range from 6% to 19%. O The stemileaf display shows that the distribution of high school dropout rates is slightly skewed to the left. A typical dropout rate is 12%. The dropout [ates range from 7% to 20%. O The stemileaf display shows that the distribution of high school dropout rates is slightly skewed to the right.
