Question 16 O out of 1 points Using the data found in Table 4, determine the efficiency for the SARTD test. Round answer to nearest tenth of a percent (i.e. 45.6%) X Efficiency = [a] Specified Answer for: a [None Given) Question 17 O out of 1 points Using the data found in Table 4 and Bayes' Formula, determine the probability that a randomly selected patient will have Strep Throat given the SARTD test result was positive. Use the CDC stated prevalence of 25%. Round answer to nearest hundredth of a percent (ie. 45.67%) P(Strep Throat Positive SARTD result) - [a] Specified Answer for: a [None Given] Question 18 O out of 1 points Using the data found in Table 4 and Bayes Formula, determine the probability that a randomly selected patient will not have Strep Throat X given the SARTD test result was negative. Use the CDC stated prevalence of 25%. Round answer to nearest hundredth of a percent (i.e. 45.67%) P(No Strep Throat Negative SARTD result) = [a] Specified Answer for: a [None Given] Sunday, June 14, 2020 1:36:03 PM MDT In an article by Forward et al (2006) published in the Canadian Journal of Infectious Diseases and Medical Microbiology, the Strep A Rapid Test Device (SARTD) was tested against conventional cultures to determine the device's effectiveness at detecting Strep A infections in patients (i.e. testing to determine if a patient has "strep throat"). The following table is based on their test results for the use of SARTD for strep throat detection in kids. Strep Pos Total Strep Neg 23 SARTD Pos 80 103 387 SARTD Neg 38 349 Total 118 372 Table 4: SARTD vs conventional culture 490 Question 16 O out of 1 points Using the data found in Table 4, determine the efficiency for the SARTD test.
