That question is accompanied by these answer choices:

<span>A. The scale is accurate but not precise.

elena-s [515]

Answer:

7.92% probability that a particular death is due to a traffic accident

Step-by-step explanation:

The relative frequency approach to find the probability that a particular death is due to a traffic accident is the number of deaths due to traffic accidents divided by the total number of deaths.

We have that:

624 deaths from traffic accidents

7883 total deaths.

So

p = \frac{624}{7883} = 0.0792

7.92% probability that a particular death is due to a traffic accident
