For a group experiment, your science class measured the fine-particulate concentrations in the air at random places around campus, and estimated a sample average of 32 μg/m3 (micrograms per cubic meter). If 225 readings were taken, and the standard deviation of the sample measurements was 3 μg/m3, you are 99.7% confident that actual concentration of fine particulates at the school is
