Answer:
Mean: 61
Step-by-step explanation:
Write out each data value represented by the stem-and-leaf plot:
a stem value of 3 with a leaf value of 1 => 31
a stem value of 4 => NIL
a stem value of 5 with a leaf value of 5 => 55
a stem value of 6 with a leaf value of 8 => 68
a stem value of 7 with a leaf value 0, 0, and 2 => 70, 70, 72
The data values are:
31, 55, 68, 70, 70, 72
✔️Mean of the values = sum of the values ÷ 6
= (31 + 55 + 68 + 70 + 70 + 72) ÷ 6 = 366 ÷ 6
Mean = 61
