At the homecoming game at a security checkpoint, 100 persons were randomly selected for extra screening to determine if they were bringing any alcohol, drugs, or weapons into the stadium (i.e., breaking the rules). We know the screening is 98% accurate when testing a person who is breaking the rules and 95% accurate when testing a person who is not breaking the rules. Suppose (if we were "all knowing") that 20 of the tested persons were in fact breaking the...

Suppose that 20% of the cyclists racing in the Tour de France are using illegal performance enhancing drugs. They are tested one week prior to the start of the race. The blood test administered has a 5% false positive rate (that is, the probability of a positive result given the individual is not using an illegal performance enhancing drug is .05). The probability of a positive result given the individual is using an illegal performance enhancing drug is .90. Suppose...

In December 1982, a report in the MMWR described three persons who had developed acquired immunodeficiency syndrome (AIDS) but who had neither of the previously known risk factors for the disease: homosexual/bisexual activity with numerous partners and intravenous drug use. These three persons had previously received whole-blood transfusions. By 1983, widespread recognition of the problem of transfusion-related AIDS led to controversial recommendations that persons in known high-risk groups voluntarily defer from donating blood. In June 1984, after the discovery of...

A new screening test for Type II diabetes was evaluated/validated based on a group of 800 persons, 20% of whom were known to have the disease based on a previous diagnosis. Validation results included the following: (1) the screening test accurately identified 140 persons as having the disease; (2) the screening test accurately ruled out 500 persons as NOT having the disease. (A) What is the estimated sensitivity of the new screening test? (B) What is the estimated specificity of...

Forty-one small lots of experimental product were manufactured and tested for the occurrence of a particular indication that is attribute in nature yet causes rejection of the part. Thirty-one lots were made using one particular processing method, and ten lots were made using yet a second processing method. Each lot was equally sampled (n = 30) for the presence of this indication. In practice, optimal processing conditions show little or no occurrence of the indication. Method 1, involving the ten...
