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. Two researchers each follow a different 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; 47; 47; 33; 34
Researcher B:
3; 14; 11; 5; 16; 17; 28; 41; 31; 18; 14; 14; 26; 25; 21; 22; 31; 2; 35; 44; 23; 21; 21; 16; 12; 18; 41; 22; 16;
25; 33; 34; 29; 13; 18; 24; 23; 42; 33; 29
Determine what the key terms refer to in the example for Researcher A.
