The mean number of fatalities, calculated by summing up fatalities for each year and dividing by the total number of years, is 1885.2, rounded to the nearest tenth.
To find the mean number of fatalities, we need to sum up the fatalities for each year and then divide by the total number of years. The formula for the mean (average) is:
Mean = Sum of fatalities / Total number of years
Let's calculate it based on the provided data:
Sum of fatalities = 13601 + 86 + 534 + 0 + 25 + 14 + 25 + 107 + 4210 + 50 = 18852
Total number of years = 10
Now, plug these values into the mean formula:
Mean = 18852 / 10 = 1885.2
Therefore, the mean number of fatalities is 1885.2 (rounded to the nearest tenth).
