Answer:
C. (36337.32, 48968.68)
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 M as such

In which
is the standard deviation of the population and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 42653 - 6315.68 = 36337.32.
The upper end of the interval is the sample mean added to M. So it is 42653 + 6315.68 = 48968.68.
So the correct answer is:
C. (36337.32, 48968.68)
Answer:
56 trees will make 10000 newspapers.
Step-by-step explanation:
Given:
One tree makes approximately 230 newspapers.
Now, for estimating how many newspapers will be made with 56 trees.
By multiplying
trees with
newspapers we get,
.
And, rounding
to one significant number (1 S.F.) is
.
Therefore, 56 trees will make 10000 newspapers.
simplifying
we get 
Step-by-step explanation:
We need to simplify: 
Solving:
Applying the rule:
log a + log b = log(ab)

So, simplifying
we get
