NikAS [45]

Answer:

The answer is 0.8788

Step-by-step explanation:

<em>From question given, let us recall the following:</em>

<em>We know that  Ƶα /2  * √p (1-p)/n</em>

<em>when we use  n≤  5000/10 =500</em>

<em> P = 0.75</em>

<em>The Margin of error = 0.03</em>

<em>Putting this values together we arrive at </em>

<em> Ƶα/2 = 0.03/√0.75 * 0.25/500 </em>

<em>= 1.549</em>

<em>Now,</em>

<em>Ф (1.549) = 0.9394</em>

<em>Therefore the confidence level becomes:</em>

<em> 1- (1-∝)/2 = 0.9394</em>

<em>∝ = 0.8788</em>

<em>The answer is 0.8788</em>

Mabel has read 3/4 of a book, or 390 pages. How many pages are in the entire book?
Arte-miy333 [17]
520 pages. 390 divided by 3 is 130. Take that times 4 and you get 520. To check it, I took 520 divided by four (or you can multiply by 1/4) and got 130. Hope it helps!
