Draw simple random samples from each group. O simple random sample O stratified sample O systematic sample O duster sample O convenience sample (b) Obtain lists of patients discharged from all MMH facilities. Number these patients, and then use a random-number table to obtain the sample. O simple random sample O stratified sample O systematic sample O duster sample O convenience sample (c) Randomly select some MMH facilities from each of five geographic regions, and then include all the patients on the discharge lists of the selected hospitals. O simple random sample O stratified sample O systematic sample O cluster sample O convenience sample (d) At the beginning of the year, instruct each MMH facility to survey every 500th patient discharged. O simple random sample O stratified sample O systematic sample O cluster sample O convenience sample (e) Instruct each MMH facility to survey 10 discharged patients this week and send in the results.
