Suppose that a test for presence of a disease is 87.5% accurate. Within a sample of 3200 patients, the incidence rate of the disease is the national average which is 14%. a) Using this information construct a table modeled after the one in the sample problem.b) Suppose a patient has a negative test result. What is the percent chance that she truly has the disease? Round your result to the nearest 0.1%.c) Suppose your friend has a positive test result. What is the percent chance that she truly has the disease? Round your result to the nearest 0.1%.d) In a well written contextual sentence directed at your friend, compare her chance of having the disease to the national average (incidence rate). Your friend does not know any statistics.e) What percent of these patients receive the correct test result
Suppose that a test for presence of a disease is 87.5% accurate. Within a sample of 3200 patients, the
incidence rate of the disease is the national average which is 14%.
a) Using this information construct a table modeled after the one in the sample problem.
b) Suppose a patient has a negative test result. What is the percent chance that she truly has the
disease? Round your result to the nearest 0.1%.
c) Suppose your friend has a positive test result. What is the percent chance that she truly has the
disease? Round your result to the nearest 0.1%.
d) In a well written contextual sentence directed at your friend, compare her chance of having the
disease to the national average (incidence rate). Your friend does not know any statistics.
e) What percent of these patients receive the correct test result
