The probability that a person has a certain disease is 0.03. If the disease is actually present, the probability that the diagnostic test will give a positive result is 0.90. If the disease is not actually present, the probability of a positive result is 0.02. Suppose that the diagnostic test has given a positive result, what is the probability that the disease is actually present? Hawra scored 90 on a math contest. Assume that contest scores are normally distributed with mean a = 85 and a standard deviation = 15. What proportion of students had a higher score than Hawra?
