Need help with a biostats question. We selected a random sample of size 110 from a pool of university....? - Dark Knight - 06-15-2014 11:45 AM
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
