Final answer:
The student's question requires data on the number of deaths per year from 2004 to 2008, which is not provided in the given statistics. The questions about frequency, percentage, and relative frequency of deaths cannot be answered accurately without specific death statistics. For presenting data, a line graph is recommended to effectively depict trends over time.
Step-by-step explanation:
The student has queried about the number of people who died each year from 2004 to 2008. The given data, however, does not directly provide the number of deaths, but rather the total number of crashes for each year. To address question 'a', which asks for the frequency of deaths from 2006 through 2009, one would need to calculate the aggregate number of crashes within this period and use additional data to find the corresponding deaths. Question 'b' inquires about the percentage of deaths occurring after 2009, which ideally requires data on the total number of deaths over the entire time span to determine this percentage. For 'c', the relative frequency of deaths that occurred in 2003 or earlier, and for 'd', the percentage of deaths in 2004, again, one would need specific data on deaths, which is not provided in the given statistics.
Regarding the student's sub-questions 'g' and 'h', it is important to clarify that without the actual death statistics or factors contributing to the large number of deaths in 2010 and 2004, we can only hypothesize that reasons might include an increase in the volume of traffic, changes in laws, or possibly natural disasters or other significant events impacting road safety. For presenting these data in an oral presentation, a line graph would be recommended as it illustrates trends over time effectively. Highlighted features would include peaks, troughs, and any notable changes year-to-year.
Lastly, it's important to note that the data provided is statistical in nature and represents crash data, not direct death counts.
