Transcribed Image Text:Q1.1 Expected Values
A study involved 2121 patients who were MRSA (methicillin-resistant staphylococcus aureus)
carriers. Upon discharge from the hospital, all patients were given information on how to avoid
infection. 1058 patients were randomly assigned special cleaning products and told to use them
for six months. At the end of the study period, 98 of the 1063 patients in the education-only group
developed a MRSA infection while 67 of the 1058 patients in the deep-clean group developed a
MRSA infection.
