She then sent out 96 friend requests and 21 of these accepted the request. Using the theory-based inference applet, find a 95% confidence interval for the proportion of all students that would accept a Facebook request from a male at their college that they did not know. Round your answers to 4 decimal places, e.g. 0.7523.
Confidence interval is ___________ to ___________________
Explanation / Answer
