A virologist and epidemiolgist has been studying the data for viral load (measured in log10 copies /mL) based on the first nasopharyngeal aspirate (taken on the day of admission of the SARS patients who were admitted within the first 6 days of the outbreak at the Amoy Gardens in Hong Kong, from March 20 to April 15, 2003*). The average viral load was 3.42 and the standard deviation was 1.5.

(a) Consider one measurement for a patient from their data. If the z-score of this measurement is -2.5, compute numerical value of the viral load of that patient.

(b) If the z-score of a measurement for a patient from this data set is positive, then is that measurement larger than 3.42 or smaller than 3.42? Explain your answer.
