Emily works at the front desk of a resort. This month she made several calls to clients using the company cellular phone. The legth of each call in minutes is shown using the stem and leaf diagram below: Stem - Leaf
1 = 0,0,0,1,1,2,2,2,4,5,5,8
2 = 0,1,2,2,4,5
3 = 4

a. what is the modal length of time of the calls in minute?
b. what is the mean length of time of calls in minute?
