Answer:
b. 224
Step-by-step explanation:
We have that to find our
level, that is the subtraction of 1 by the confidence interval divided by 2. So:

Now, we have to find z in the Ztable as such z has a pvalue of
.
So it is z with a pvalue of
, so 
Now, find the margin of error M as such

In which
is the standard deviation of the population and n is the size of the sample.
In this problem:
We want to find n, when
So






The nearest integer number to 223.9 is 224.
So the correct answer is:
b. 224
<span> √3 - i = 2e^(5πi/6)
(2e^(5πi/6))^-10 = 2^-10 * e^(-25πi/3)
= 2^-10 * (cos(-25π/3) + isin(-25π/3))
= 2^-10* (1/2 - i(√3/2)) </span>
