QUESTION 11

1. In Golestanehet al, Figure 2 shows a plot that might be improved based on the principles that we learned in this class. It is a line graph, where there might be a better choice for the type of graph.

Why is a line graph not the best choice? If you were to choose a different type of graph, what would you choose and why?

QUESTION 12

1. Dr. Wendy McDonald is continuing her COVID studies based onGolestanehet al.

Golestaneh explores how race plays a role in COVID mortality. Many of the analyses conducted try to control for underlying comorbid factors, like pre-existing obesity or asthma. Wendy McDonald would like to perform different analysis using conditional probabilities.

She defines:

P(D) = probability of dying from COVID, P(A) = probability of having asthmaandP(O) = probability of being morbidly obese

Which of the following statements are true?

		P(D|A) = P(A|D)x P(A)
		P(D|A) =P(A|D)x P(D)/P(A)
		P(A|D)=P(D|A)x P(A) / P(D)
		P(D)= P(D|A) x P(D) /P(A)
