Question
Question 1 - General Probability Question. Consider the following questions based on the following data: P (A=Hypertension) = 0.81 P (A=Hypertension B=Diabetes) = 0.35 P
Question 1 - General Probability Question. Consider the following questions based on the following data:
P (A=Hypertension) = 0.81
P (A=Hypertension B=Diabetes) = 0.35
P (B=Diabetes) = 0.43
- What is the probability of Hypertension or B=Diabetes occurring, P(A=Hypertension=Diabetes)?
- What is the probability of A=Hypertension occurring given that B=Diabetes has occurred (i.e. P (A=Hypertension|B=Diabetes)? That is to say, a person has Hypertension given they are diabetic.
- Are the two events, Hypertension and Diabetes, disjoint (i.e. mutually exclusive)? Explain with values.
- Are the two events independent? That is to say, is there evidence that having Hypertension influences presence of diabetes (or vice versa). Explain with values.
Question 2 General probability with Counts - Suppose you have the following Health Data on a group of patients who went to an OUHSC clinic in 2023.
Age \ Obesity | Normal Weight | Overweight/Obese | Totals |
Under 45 | 347 | 749 | 1096 |
45 or Over | 628 | 803 | 1431 |
Totals | 975 | 1552 | 2527 |
a) What is the probability of overweight/obese given under 45? That is P(overweight/obese | Under 45)?
b) Are obesity and age independent of one another? Explain with your calculations.
c) What is P(Under 45 U Normal weight)? Show your calculation.
