It already is in simplest form because the numerator and denonimator don't have a common factor to then divide them by.
Answer:
1. Five classes in the frequency distribution
2.The mid point of the third class is 24.5
3.The total number of frequency is 100
4.The relative frequency of the third class is (20/100=0.2)
5. We use n-1 because we are dealing with a sample data
6. The mean is 24.5
7. The value of the standard deviation is 11
Step-by-step explanation:

P/2 = l +w
make w the subject of the formula
P/2 - l =w
w = P/2 - l
