Transcribed Image Text:A medical geographer in Kenya is studying the distribution of an infectious strain of
"sleeping sickness". She believes it should be more prevalent among human
populations that live in river floodplains. Data were collected on the number of
infections from a random sample of 100 people on a floodplain and a second sample
of 125 people living in an adjacent highlands area. 10 people from the floodplain and
8 people from the highlands were found to be infected.
Based on this information, the researcher can be 90% confident that the floodplain
population is at greater risk of infection.
