Studies are often done by pharmaceutical companies to determine the effectiveness of a treatment program. Suppose that a new AIDS antibody drug is currently under study. It is given to patients once the AIDS symptoms have revealed themselves. Of interest is the average (mean) length of time in months patients live once they start the treatment. A researcher follows a set of 40 patients with AIDS from the start of treatment until their deaths. The following data (in months) are collected. Researcher A: 3; 4; 11; 15; 16; 17; 22; 44; 37; 16; 14; 24; 25; 15; 26; 27; 33; 29; 35; 44; 13; 21; 22; 10; 12; 8; 40; 32; 26; 27; 31; 34; 29; 17; 8; 24; 18; 47; 33; 34 Identify the (i) target population, (ii) variable of interest, (iii) parameter of interest, (iv) sample, (v) sample size, and the (vi) sample statistic.

Transcribed Image Text:Studies are often done by pharmaceutical companies to determine the effectiveness of a treatment
program. Suppose that a new AIDS antibody drug is currently under study. It is given to patients
once the AIDS symptoms have revealed themselves. Of interest is the average (mean) length of
time in months patients live once they start the treatment. A researcher follows a set of 40 patients
with AIDS from the start of treatment until their deaths. The following data (in months) are
