Answer:
a) The modal class for this case represent the class with the highest frequency
And for this case would be
with the highest frequency 8
b) 
Step-by-step explanation:
Part a
The modal class for this case represent the class with the highest frequency
And for this case would be
with the highest frequency 8
Part b
For this case we need to find the mid point of each interval:
Interval Midpoint Frequency
18-20 19 3
20-22 21 2
22-24 23 7
24-26 25 8
And we can find the sample mean with this formula:

And replacing we got:
