1) A school has 1600 students and they are going to vote as to whether they will completely convert the school completely off fo
fredd [130]

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

                      M.E = \frac{Z_{0.05} S.D}{\sqrt{n} }

Level of significance = 0.05

Z₀.₀₅ = 1.96

Given Margin of error = 2% = 0.02

       M.E = \frac{Z_{0.05} S.D}{\sqrt{n} }

       0.02 = \frac{1.96 X S.D}{\sqrt{1600} }

      0.02 X √1600 = 1.96 X S.D

       S.D = \frac{0.02X\sqrt{1600} }{1.96} = 0.408

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
