Question

NOTE: PLEASE FOLLOW SLOVIN’S FORMULA IN THE PHOTO ATTACHED.

2. (Use Slovin's Formula) A researcher would like to survey 3,000 college students
for his/her study. If he/she wants to be 99% precise with the study, how many
students are to be considered?
Solution
Interpretation

Slovin's Formula
Where:
n =
N
1+ Ne²
n = sample size
N = population size
e = margin of error (usually 0.05 or 5%)
N
1+Ne²
Example: Compute a sufficient sample size of a target population consisting of 1,524
junior high school students using Slavin's Formula.
Solution:
n =
1524
1524
1524
1+(1524) (05)² 1+(1524)(.0025) 1+3.81
=
1524
4.81
= 316.839168 = 317
