The question is an illustration of composite functions.
- Functions c(n) and h(n) are
and
- The composite function c(n(h)) is
- The value of c(n(100)) is
- The interpretation is: <em>"the cost of working for 100 hours is $130000"</em>
The given parameters are:
- $5000 in fixed costs plus an additional $250
- 5 systems in one hour of production
<u>(a) Functions c(n) and n(h)</u>
Let the number of system be n, and h be the number of hours
So, the cost function (c(n)) is:
This gives
The function for number of systems is:
<u>(b) Function c(n(h))</u>
In (a), we have:
Substitute n(h) for n in
Substitute
<u>(c) Find c(n(100))</u>
c(n(100)) means that h = 100.
So, we have:
<u>(d) Interpret (c)</u>
In (c), we have:
It means that:
The cost of working for 100 hours is $130000

Answer:
The confidence interval is (0.444 ± 0.111).
Step-by-step explanation:
The general form of a confidence interval for single proportion is:
The interval provided is: (0.333 < p < 0.555)
Then
Solving the two equation simultaneously:
Add (i) and (ii),
Substitute the value of in (i) to compute the value of <em>E:</em>
Thus, the confidence interval is,
