The following stem-and-leaf plot represents the distribution of weights for a group of people. Step 1 of 3 : What is the weight of the lightest person in the group?

Answer
In a stem-and-leaf plot, each numerical data value is split into a 'stem' (the leading digits) and a 'leaf' (the final digit). The key provided at the bottom of the plot states that '10 | 1 = 101 pounds', which confirms the stem represents the hundreds and tens digits, while the leaf represents the units digit. To find the weight of the lightest person, we look for the smallest stem and the smallest leaf associated with that stem. In this plot, the stems are listed in increasing order. The smallest stem is 10. For stem 10, the leaves are 1, 3, 5, and 5. The smallest leaf is 1. Combining the stem of 10 with the leaf of 1 gives a weight of 101 pounds. Therefore, the weight of the lightest person in the group is 101 pounds.
