The lower class boundary of the fish is the average of the lower limit of the class in question and the previous upper limit
The lower class boundary of the first class is 99.5
From the complete question, we have the first and the second classes to be:
100 - 114
115 - 129
The difference between the upper limit of a class and the lower limit of the next class is 1. i.e. 115 - 114 = 1
Half of 1 is 0.5
The lower class limit of the first class is 100
Subtract 0.5 from 100 to determine the lower class boundary of the first class
Lower = 100 - 0.5
Evaluate the difference
Lower = 99.5
Hence, the lower class boundary of the first class is 99.5
