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>

Dmitry_Shevchenko [17]

<u><em>Answer:</em></u>

Elliot biked 70 miles

<u><em>Explanation:</em></u>

We are given that the total distance of the race is 100 miles

We are also given that Elliot covered \frac{7}{10} of this distance

To get the number of miles covered by Elliot, we will simply multiply the ratio of the covered distance (\frac{7}{10}) by thetotal distance of the race (100 miles)

<u>This is done as follows:</u>

Distance covered = \frac{7}{10} * 100 = 70 miles

<u>Therefore,</u> Elliot biked for 70 miles

Hope this helps :)
