Not sure if this is correct but:
Step-by-step explanation: P = 2000
R = 5% = 0.05
n = 4
y = 2000 ( 1 +
)
= 2000 ( 1.0125 )
Substitute values in the compound interest formula:
y = P ( 1 +
)
.
Hope this helps..
We need convert the mixed numbers to improper fractions.

Answer:
C.25
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.
Which of the following is the smallest sample the company can take to achieve the desired margin or error?
This is n when 






We have to round up.
So the correct answer is:
C.25
