Suppose a lab is developing a robust new test to look for diabetes in children. If a child actually has diabetes, the probability that the test will be positive is 84%, indicating they have diabetes. If the child does not have diabetes, the probability that the test will be positive is 11%. Suppose 5.3% of all children actually have diabetes. (Round your answer to 3 decimal places, if needed.)
a) What is the probability that a randomly chosen child has diabetes and tested positive?
b) What is the probability that a randomly chosen child tested positive?
c) Given that a test comes up positive, what is the probability the child has diabetes?
d) What is the probability that a randomly chosen child does not have diabetes and tested negative?
e) What is the probability that a randomly chosen child tested negative?
f) Given that a test comes up negative, what is the probability the child does not have diabetes?
