Where
m
is the slope and (

) are the two points on the line.
Substituting the values from the points in the problem gives:

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:
See attached picture for the solutions
115 is the outlier, and it results in the mean being lower than it would have been.
