(a) Discuss why screening strategies should be recommended for monitoring indoor air quality (IAQ) in air-conditioned offices in Hong Kong. (8 marks) (b) Given the screening level of airborne bacteria level is 1000 CFU/m³, the pre-assessment odds is 0.3, and the expected bacteria level in CFU/m³ is 0-0.022T2.441.2, where T is air temperature (°C) and is relative humidity (%), the likelihood ratio of excessive airborne bacteria counts is 3x10-1204, determine the increment of the post-assessment probability of positive outcomes of an air-conditioned office set-point shifting from T-23.5°C and -50% to 25.5°C and 60%. (12 marks) (c) For the office in (b) at T=25.5°C and 0-60%, a screening test showed a negative test result (980 CFU/m³). The probabilities of larger than the baseline of 1000 CFU/m³ of failure and non-failure offices are 0.2 and 0.8, respectively. Determine the probability of tested false negative.
