Provide an appropriate response.The parallel dot plots show the number of fatalities per year caused by tornadoes in a certain state for two periods: 1950-1974 and 1975-1999. In addition to comparing these distributions, suggest a reason to explain any differences. 
A. In both periods, the number of fatalities per year ranges from 0 to 5. During the period 1950-1974, the most common number of fatalities was 2. The distribution for this period is roughly symmetric - the number of years having more than 2 fatalities is roughly the same as the numbers of years having fewer than 2 fatalities. During the period 1975-1999, the most common number of fatalities is 0 and most years have 0 or 1 fatality. Only a few years have more than 1 fatality during this period. This could be due to higher construction standards, better warning systems, or medical advancements. B. In both periods, the number of fatalities per year ranges from 0 to 5.

During the period 1950-1974, the most common number of fatalities was 3. The distribution for this period is roughly symmetric - the number of years having more than 3 fatalities is roughly the same as the numbers of years having fewer than 3 fatalities. During the period 1975-1999, the most common number of fatalities is 0 and most years have 0 or 1 fatality. Only a few years have more than 1 fatality during this period.
