Explanation:

Step1: Calculate case - fatality rate

The case - fatality rate is the proportion of people with a disease who die from that disease. It is calculated as the number of deaths due to the disease divided by the number of people with the disease, then multiplied by 100 to get a percentage.
The number of people with E.coli is 287 and the number of deaths is 69.
Case - fatality rate=$\frac{69}{287}\times100$

Step2: Calculate cause - specific death rate

The cause - specific death rate is the number of deaths due to a specific cause (E.coli in this case) divided by the total population, then multiplied by 1000 to express it per 1000 individuals.
The total population is 1500 and the number of deaths due to E.coli is 69.
Cause - specific death rate=$\frac{69}{1500}\times1000$
