In a local university, 40% of the students live in the dormitories. A random sample of 80 students is selected for a particular study. The standard deviation of the sample propotion is known as the standard error of the proportion is approximately
----------------------------
standard deviation = sqrt[p*q/n]
---
= sqrt[0.4*0.6/80]
---
= sqrt[0.003]
---
= 0.05478...
