Consider the following two clinical trials concerning an investigational drug given for the treatment of cancer. #1: 100 people are administered the drug and 40 of the people respond. #2: 60 people are administered the drug and 24 of those people respond. Both trials have a 40% response rate. Construct a 95% confidence interval for the response rate for each trial. Which trial has a narrower confidence interval? a. Clinical trial #1 b. Clinical trial #2 c. The confidence intervals are the same width d. Unable to determine without additional information
