Question 9 – 11

Short Essay

1. Compare and contrast binomial and normal distributions. Give an example of each being used in a public health setting. You do not need to provide calculations but rather, a summary of the scenario and the data to which the distribution would be applied and evaluated. Your essay should be at least 250 words in length.

2. Explain in your own words how probability laws and concepts are used in the evaluation of screening tests and diagnostic criteria in public health. Offer two examples to support your explanation. You do not need to provide calculations but rather, a summary of the scenario and the data to which the distribution would be applied and evaluated.

3. Explain in your own words the difference between a random experiment and a trial. Illustrate each by giving a real-world example of how each has been applied in a public health setting in the last decade. Be sure to include specifics to validate your claim in at least 250 words
