Students at a certain school were​ surveyed, and it was estimated that 10​% of college students abstain from drinking alcohol. T
MissTica

Answer:

a)

<em> you are unwilling to predict the proportion value at your school  = 0.90</em>

<em>b) </em>

<em>The large sample size 'n' = 864</em>

<em></em>

Step-by-step explanation:

Given estimated proportion 'p' = 10% = 0.10

<em>Given Margin of error M.E = 0.02</em>

<em>Level of significance α = 0.05</em>

a)

<em>  you are unwilling to predict the proportion value at your school </em>

<em>   q = 1- p = 1- 0.10 =0.90</em>

b)

<em>The Margin of error is determined by</em>

                        M.E = \frac{Z_{\frac{\alpha }{2} } \sqrt{p(1-p)} }{\sqrt{n} }

                       0.02 = \frac{1.96 X \sqrt{0.10 (0.90)} }{\sqrt{n} }

Cross multiplication , we get

                      \sqrt{n}  = \frac{1.96 X \sqrt{0.10 (0.90)} }{0.02 }

                      √n  = 29.4

<em>Squaring on both sides , we get</em>

<em>                      n = 864.36</em>

<u><em>Conclusion</em></u><em>:-</em>

<em>The large sample size 'n' = 864</em>

<em></em>
