Answer:
Standard deviation of the students = 0.408
The students would you have to poll to be 95% confident of the outcome within /- 2% of the vote
= 0.408 X 1600
= 652.8
Step-by-step explanation:
<u><em>Step(i):</em></u>-
Given sample size 'n' = 1600
95% confidence interval of the margin error is determined by

Level of significance = 0.05
Z₀.₀₅ = 1.96
Given Margin of error = 2% = 0.02


0.02 X √1600 = 1.96 X S.D

Standard deviation of the students = 0.408
The students would you have to poll to be 95% confident of the outcome within /- 2% of the vote
= 0.408 X 1600
= 652.8

Step-by-step explanation:
Given
If there are r red counter and g green counter then
Probability of drawing a green counter is 
and 
Thus 



Also if 4 red and 2 green counter is added the probability of drawing a green counter is





Substitute the value of g in equation (ii)[/tex]



Therefore 
Thus there 28 green counter and 35 red counter
