Which one is it
### Distribution of Major Hurricanes This section provides a probability distribution for the number of major hurricanes, \( X \), for a randomly selected year between 1851 and 2017. Complete the following analysis based on the data provided. #### Task: a. Find and interpret the mean of the random variable \( \mu \). ```plaintext \mu = 2.175 (Round to three decimal places as needed) ``` b. Find the standard deviation of the random variable \( \sigma \). ```plaintext \sigma = 1.303 (Round to three decimal places as needed) ``` #### Analysis Questions: 1. Interpret the mean value in context of the data. - The average number of major hurricanes per year is approximately 2.175. 2. Interpret the standard deviation in context of the data. - The typical deviation from the average number of major hurricanes per year is approximately 1.303, indicating variability in the yearly counts. 3. The Table: - The table provided shows the probability distribution of the major hurricanes. #### Probability Distribution Table: The table below displays \( X \) as the number of major hurricanes and \( P(X) \) as the probability of occurrence. | X | P(X) | |----|-------| | 0 | 0.042 | | 1 | 0.125 | | 2 | 0.258 | | 3 | 0.272 | | 4 | 0.142 | | 5 | 0.092 | | 6 | 0.042 | | 7 | 0.021 | | 8 | 0.005 | From this table, it is evident that: - The most common number of major hurricanes in a year is 3. - The likelihood of having no major hurricanes in a given year is 4.2%. This study helps to understand the historical distribution and frequency of major hurricanes in the specified period.
