In order to evaluate the diagnostic accuracy of a new rapid test for Tuberculosis,results of the screening test were compared to the Reference golden standard(confirmatory test) in 20,000 patients. From 1200 individuals who tested positiveby the rapid test, only 400 were confirmed +ve. From 18800 individuals whotested negative by the rapid test, 1200 were confirmed tuberculosis -ve. ThePositive predictive value and the Negative predictive value of this screening testare:O PPV-0.333 & NPV30.064O PPV=0.667 & NPV=0.936O PPV=0.936 & NPV-0.667PPV=0.064 & NPV30.333 Find the outliers in the following data : 280-500-300-450-330-370-400O No outlierO 550 onlyO 280 only280 and 550

given, 400 +ve confirmed from 1200. 1200 +ve confirmed from 18800.

Average IQ scores for young school children are known to be 100 (SD = 15). However, the literature indicates that children’s intelligence may be decreased if their mothers have German measles during pregnancy. Using hospital records, a researcher obtained a sample of n = 25 school children whose mothers all had German measles during their pregnancies. Do the data indicate that children born to mothers who had German measles during the pregnancy have significantly lower IQ scores than typical young school children?

A certain drug can be used to reduce the acid produced by the body and heal damage to the esophagus due to acid reflux. The manufacturer of the drug claims that more than 91% of patients taking the drug are healed within 8 weeks. In clinical trials, 212 of 229 patients suffering from acid reflux disease were healed after 8 weeks. Test the manufacturer's claim at the a= 0.05 level of significance. Because npo (1-Po) = 0.2 > 10, the sample size is less than 5% of the population size, and the sample can be reasonably assumed to be random, the requirements for testing the hypothesis are satisfied.
