Use the data below to construct a stem and leaf display on your own paper, then describe the distribution's shape

So for example 50 65 68 72 74 78 80 82 83 84 90 91 92 92 92 92 93 94 95 97 98 98 99 99 100 100.
if we use that we could make this.
   Stem                           Leaf
   5                                   0
   6                                   5 8
   7                                   2  4  8
   8                                   0  2  3  4
   9                                   0  1  2  2  2  2  3  4  5  7  8  8  9  9
   10                                 0  0
                              

The answer is 41.7 because 1.39 times 30 is 41.7
