A researcher conducted a medical study to estimate the difference in the rates of the development of colon cancer for patients that took a low dose aspirin daily compared to patients that did not. As part of the study, 1,000 adult volunteers were randomly assigned to one of two groups. Half of the volunteers were assigned to the experimental group that took a low-dose aspirin each day, and the other half were assigned to the control group that took a placebo each day. At the end of six years, 15 of the people who took the lowdose aspirin had developed colon cancer and 26 of the people who took the placebo had developed colon cancer. At the 90% level of confidence, which of the following indicates the difference in the rates of the development of colon cancer for patients taking a low dose aspirin compared to patients that did not?
A) .03 to .052
B) -.047 to .0025
C) -.054 to .0103
(D) -.043 to -.001
E) -.0025 to .047
