Answer: There are 4 threes would be listed in the leaf area of a stem and leaf plot.
Explanation:
Since we have given that the following data:
12, 12, 22, 23, 33, 34, 36, 37,48, 47
For 1: 12,12
For 2: 22, 23,
For 3 : 33, 34, 36, 37
For 4: 48, 47
So, the stem and leaf plot will be
Stem Leaf
1 2, 2
2 2, 3
3 3,4,6,7
4 8, 7
Hence, there are 4 threes would be listed in the leaf area of a stem and leaf plot.
