The histogram shows the distribution of hurricanes that have hit a country from 1851 through 2015, where 1 is the weakest level and 5 is the strongest level.
1= 0.411
2=0.278
3=0.221
4=0.080
5=0.010
(a) Find the mean, variance and standard deviation of the probability distribution.
(b) Interpret the results: A, B, C or D.
A. The average hurricane is aprox. category 1.
B. The average hurricane is aprox. category 2.*
C. Most of the hurricane sizes differ from the average by about 2 or 3.
D. Most of the hurricane sized differ from the average by about 1 or 2.*
