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>

Add 25 to both sides:
Square root both sides.
When you square root a perfect square, you will get a plus/minus result:
The other solution to this answer is x = -5.
When £13000 is increased by 11% the new value becomes to £14430
The number 15 has 2 place values.
The value in the tens place is 1.
The value in the ones place is 5.
1 tens + 5 ones = 15
