Answer:
The lower limit of 95% confidence interval is 99002.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = $100,000
Sample mean,
= $111,000
Sample size, n = 36
Alpha, α = 0.05
Population standard deviation, σ = $36,730
First, we design the null and the alternate hypothesis

We have to find the lower limit of the 95% confidence interval.
95% Confidence interval:

Putting the values, we get,


The lower limit of 95% confidence interval is 99002.
I would say the answer is C
ANSWER

EXPLANATION
Given:

and

Then,

Substitute the given functions;

Factor



Cancel the common factors.

Let's say x = 16. In the equation 4 + x(3/x) then you use 16 instead of x. So it would look like 4 + 16(16/3). 4 plus 16 times 16 divided by 3.
