Answer:

  • quartiles: 43, 56
  • median: 50

Step-by-step explanation:

A stem-and-leaf plot is a kind of histogram in which the most significant digit of a data value is taken to be the "stem", and the "leaves" are a list of the least-significant digits of the data values. It is convenient to list the leaves in increasing order, to facilitate determining the quartiles in the data.
