Cloud [144]
1) When it says more than, then you have to switch it so it will be 7n + 1 instead of 1+7n.
2) Because you then have to subtract by 5 you have to put the 7n + 1 in parentheses so it reads (7n + 1) - 5
3) And then to evaluate you just have to substitute n for 6
4) 7 * 6 = 42; 42+1 = 43; 43-5 = 38
5) The answer to this expression would be 38

Hope it helps :)

77julia77 [94]

Answer:

<em>The number of people would have participate in opinion poll</em>

<em>n =  15,267</em>

Step-by-step explanation:

<u><em>Step(i)</em></u>:-

Given data an opinion poll reported that 36% believe a certain governor broke campaign financing laws in his election campaign.

<em>Given proportion = 36% =0.36</em>

<em>Given the margin of error = 1% =0.01</em>

<em>Level of significance = 99% 0 r 0.01</em>

<em>Z₀.₀₁ = 2.576</em>

<u><em>step(ii):</em></u><em>-</em>

<em>The margin of error of Population proportion is determined by</em>

M.E = \frac{Z_{0.01} \sqrt{p(1-p)} }{\sqrt{n} }

0.01 = \frac{2.576 \sqrt{0.36(1-0.36)} }{\sqrt{n} }

\sqrt{n}  = \frac{2.576 \sqrt{0.36(1-0.36)} }{0.01 }

√n =  123.648

Squaring on both sides , we get

<em>n =  15,267</em>

<u><em>final answer:</em></u><em>-</em>

<em>The number of people would have participate in opinion poll</em>

<em>n =  15,267</em>
