Answer:
Step-by-step explanation:
Given is the list the highway gas mileages (in miles per gallon)
22, 24, 26, 26, 28, 28, 29, 30, 30, 30, 31, 34, 34, 34, 34, 35, 36, 36, 41, 41
We construct stem and leaf plot as follows:
Stem Leaf
2 2 4 6 6 8 8 9
3 0 0 0 1 4 4 4 4 5 6 6
4 1 1
b) 34th percentile = 34*20/100 = 6.8th entry
i.e. in ascending order,
7th entry = 29 is the 34th percentile.
