Answer:
The fraction is = 
Step-by-step explanation:
In simplest form the fraction is represented in mixed number as 
.
The fraction form of the mixed number can be given as :
Let the fraction be = 
[As multiplying same numbers to numerator and denominator does not affect the proportion.
Sum of numerator and denominator is = 30
This, can be represented as:
Solving for 
.
Dividing both sides by 10.
So, the fraction will be = 
⇒
Margin of error, e = Z*SD/Sqrt (N), where N = Sample population
Assuming a 95% confidence interval and substituting all the values;
At 95% confidence, Z = 1.96
Therefore,
0.23 = 1.96*1.9/Sqrt (N)
Sqrt (N) = 1.96*1.9/0.23
N = (1.96*1.9/0.23)^2 = 262.16 ≈ 263
Minimum sample size required is 263 students.
