Answer:
If the epidemiologist Dr. Thompson wants to assess the intoxication rate, evaluating the number of people intoxicated over the number of people who eat at the event, since they have attended the event does not mean that they have all eaten the event food.
Step-by-step explanation:
Whenever we want to evaluate the rate, we will be relating to the frequency of what happened in a given time and over a given population.
The rate will always measure the relationship of one event to another, in this case in the poisoning rate we measure the event of those who ate food, with those who became intoxicated.
