Answer:
Last part 24x
Step-by-step explanation:
I understand some of this, like the last question. if each class had 24 pupil, and were trying to find out how many are in each class, it would be 24x (x stands for the amount of classes)
You have not given a true amount of pupils so I can not give a 100% correct answer for the first part.

Answer:
CV = coefficient of variation = 0.761
Step-by-step explanation:
The coefficient of variation is defined as the standard deviation divided by the mean of a population, which in this case,
standard deviation = 15.6
mean = 20.5
CV = coefficient of variation = 15.6/20.5 = 0.761
Note that if the 16 values form a sample (i.e. not the entire population), the above result is an estimate of the CV.
