What is the relative frequency of deaths that occurred in 2003 or earlier? State answer as a decimal, rounded to the nearest hundredth.
To find the relative frequency of deaths that occurred in 2003 or earlier, we need to find the sum of the deaths from 2000 to 2003 and divide it by the total number of deaths.
The sum of deaths from 2000 to 2003 can be calculated by adding the deaths for each year:
231 + 21,357 + 11,685 + 33,819 = 67,092
To find the relative frequency, we divide the sum of deaths from 2000 to 2003 by the total number of deaths and round the result to the nearest hundredth:
Relative Frequency = (67,092 / 823,346) ≈ 0.0815
So, the relative frequency of deaths that occurred in 2003 or earlier is approximately 0.08.
