Question

In order to determine who would accept a Facebook friend request from someone they didn’t know, a student researcher made up a phoney Facebook profile that represented a male student at her college. She then sent out 100 friend requests and 22 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.

Answer 1

Solution:-

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 is C.I = ( 0.1388, 0.3012).

C.I = 0.22 + 1.96*0.041425

C.I = 0.22 + 0.08119

C.I = ( 0.1388, 0.3012)
