a. For a population of patients similar to those described in the stem of this problem, use your chart find the probability that a randomly chosen patient tests positive for strep throat. Write you answer as an abbreviated probability statement with your answer to four decimal places without using a percent symbol. For example, P(strep) = 0.16 b. For a population of patients similar to those described in the stem of this problem, use your chart find the probability that a randomly chosen patient has strep throat AND tests positive. Write you answer as an abbreviated probability statement with your answer to four decimal places without using a percent symbol. For example, P(strep) = 0.16 c. For a population of patients similar to those described in the stem of this problem, use your chart find the probability that a randomly chosen patient actually has strep throat, given that they have tested positive. Write you answer as an abbreviated probability statement with your answer to four decimal places without using a percent symbol. For example, P(strep) = 0.16

![A rapid strep test is often given in a clinical setting so that, if needed, antibiotics can begin as soon
as possible. Researchers at Cochrane.org evaluated the effectiveness of rapid strep tests and
found that one type had a sensitivity (ability to correctly detect people with strep) of 85.5% and a
specificity (ability to correctly identify people who do NOT have strep) of 95%.
Has strep throat
Does not have strep

On your own piece of paper, make a copy of the chart. Then fill in the values, assuming that you
have a group of 100,000 people, 16% of whom actually have strep throat. (You might hear the
value 16% called the base rate.)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F71475c2c-9e7c-4d61-b520-b4568846343a%2Fba78d93b-29a0-4a78-8ab0-59b396d4088f%2Fpdpn0ur_processed.png&w=3840&q=75)
