Problem No. 1
Studies are done by different pharmaceutical companies around the world to determine
the effectiveness of a treatment program. Suppose that a new COVID-19 antibody drug is
currently under study. It is given to patients once the COVID-19 symptoms have revealed
themselves. The interest of the study is the average (mean) length of time in months
patients live once they start the treatment. Two researchers each follow a different set of
40 patients with COVID-19 from the start of treatment until their deaths. The following data
(in months) are collected.
