Answer:
<h2>£8.77</h2>
Step-by-step explanation:
100 - 16 = 84
84 / 100 = 0.84
10.44 x 0.84
=8.77
The sample size must be 543 so the sample proportion is will not differ by 5%
We are given the following in the question:
Margin of error = 5%
Confidence interval:
p ±z√(p'(1 - p')/n)
Margin of error =
p = ±z√(p'(1 - p')/n)
Since no particular proportion is given, we take
p' = 0.5
Z critical at α 0.02 is ± 2.33
Putting values, we get,
p = ±z√(p'(1 - p')/n)
2.33 x √(0.5(1 - 0.5)/n)
√n = 2.33x 0.5/0.05
n = 542.89 = 543
Thus, the sample size must be 543 so the sample proportion is will not differ by 5%

Answer:
1600
Step-by-step explanation:
<h3>
(-2)^{4} x (-10)^{2}[/tex]</h3><h3>
</h3><h3>
Evaluate it: 2^{4} x -10^{2}</h3><h3>
Multiply: 16x100</h3><h3>Finally you get:</h3><h3>1600</h3>
You cannot make make an equation using a vertical line because the slope itself is undefined.
