Answer:
The range of ages is found:
D.46
Step-by-step explanation:
Age of college professors is given by a stem and leaf plot such that:
3| 0 2
4| 1 4 4 5
5| 3 5 8 9
6| 2 2 2 5 6 8
7| 5 5 6
Where the numbers on the left side shows the number at 10s place of a certain age, while number on the right side shows that number at Units place. e.g
3| 0 2
It shows ages of:
30 and 32
Range = Largest number in stem and left plot - Smallest number in stem and leaf plot
Range = 76 - 30
Range = 46
