Jamie measures the masses of two orange samples, type A and type B. The stem-and-leaf diagram displays the mass, in grams, of each of 30 oranges of type A.
Stem-and-leaf diagram:
17 | 6 8 8 9
18 | 0 1 2 2 4 7
19 | 1 2 2 3 6 7 8
20 | 0 2 5 5 5 6 7 7 8
21 | 1 5 6 8
In the key, 17|6 stands for 176 grams.
The table gives:
Mean (g): Type A = 195.7, Type B = 215.8
Range (g): Type A = (blank), Type B = 35.
