Solution:
X is the midpoint of the
class. It is adding the class limits and divide by 2.Median and Interquartile Range -Grouped Data
Step 1:
Construct the cumulative frequency distribution.
Step 2:
Decide the class that contain the median.
Class Median
is the first class with the value of cumulative frequency equal at least n/2.Step 3:
Find the median by using the following formula:

m m n-F2=L +if m L m fWhere:
n = the total frequency F = the cumulative frequency before class median i = the class width = the lower boundary of the class median= the frequency of the class medianTime to travel to workFrequency
