Determine a sample size with confidence level of 95% that will show the true proportion of population ?

A central university has a student population of 60,000. The university is interested in determining what proportion of them is in favour of a new grading system. Determine a sample size with confidence level of 95% that will show the true proportion of population in favour of the new system within plus and minus 0.02.





Determine a sample size with confidence level of 95% that will show the true proportion of population ?
Margin of error at 95% confidence = 0.98/鈭歯





0.98/鈭歯 = 卤0.02


0.98 = 卤.02 鈭歯


鈭歯 = 卤49


n = 2401Determine a sample size with confidence level of 95% that will show the true proportion of population ?
Curious on the solution approach.... where is the total population of 60000 considered ?
