Answer:
3 volunteers
Step-by-step explanation:
According to the given data:
The data represents the signatures collected by different volunteers are as following:
A stem value of 1 with a leaf value of 6 ⇒ 16
A stem value of 2 with a leaf value of 5, 6 ⇒ 25 , 26
A stem value of 3 with a leaf value of 8 ⇒ 38
A stem value of 4 with a leaf value of 0, 0, 0, 4 ⇒ 40 , 40 , 40 , 44
A stem value of 5 ⇒ no data
A stem value of 6 with a leaf value of 7 ⇒ 67
So, the total data are:
16 , 25 , 26 , 38 , 40 , 40 ,40 , 44 , 67
→How many volunteers collected fewer than 30 signatures?
So, the signatures less than 30 are 16 , 25 , 26
So, There are 3 volunteers collected fewer than 30 signatures.
