Answer:
1.165.
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 have that:
. So
So the correct answer is:
1.165.

Hi there!
f(x) = x + 5
1. y = x + 5
Switch places from x and y.
2. x = y + 5
Subtract 5.
3. x - 5 = y
Switch sides.
4. y = x – 5
Now we've found our answer.
