We selected a random sample of size 110 from a pool of university students and asked whether they use Facebook on a regular basis. Sixty replied yes. What would be your estimation of the standard error of the sample proportion of regular Facebook users based upon the given information?
0.002
0.047
0.064
0.247

p = 60/110

standard error = √[(60/110)(1 - 60/110) / 110]

= 0.047

hope that helped
