Answer:
A sample size of at least 737 specimens is required.
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 width M as such

In which
is the standard deviation of the population and n is the size of the sample.
In this problem, we have that:

So:





A sample size of at least 737 specimens is required.
Answer:
D. (2 , 1)
Step-by-step explanation:
STEP 1: Replace all occurrences of
with
in each equation.

STEP 2: Solve for
in the first equation.

STEP 3: Replace all occurrences of
with
in each equation.

Answer: 7
Step-by-step explanation: First, simplify what's inside the parentheses.
(3 + 3) simplifies to 6 and (-2 + 3) simplifies to 1.
Now we have 6 + 1 or 7.
n/0.2=-10
Goal: Make n by itself!
Solution: We can do this by multiplying each side by -0.2
-10 * -0.2=2
