In August 1976, tuberculosis was diagnosed in a high school student (index case) in Corinth, Mississippi. Subsequently, laboratory studies revealed that the student's disease was caused by drug-resistant tubercule bacilli. An epidemiologic investigation was conducted at the high school. Table E4.6 gives the rates of positive tuberculin reaction, determined for various groups of students according to degree of exposure to the index case. Calculate the upper bound of the 95% confidence interval for the rate of positive tuberculin reaction with low exposure level. Provide your answer in 4 decimal places. See pages 153-157 of our textbook. Exposure Number Number Level Tested Positive High 127 69 Low 318 36
