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
Asuming the added image is part of the complete question...

Answer:
C. 21.25 ( i'm assuming that C. says 21.25)
Step-by-step explanation:
Since it's an isosceles triangle, the two bottom angles are equal to one another. So 180 - 75 = 105. 105 ÷ 2 = 52.5
2x + 10 = 52.5
2x = 42.5
x = 21.25
