Answer:
First question: LCL = 522, UCL = 1000.5
Second question: A sample size no smaller than 418 is needed.
Step-by-step explanation:
First question:
Lower bound:
0.36 of 1450. So
0.36*1450 = 522
Upper bound:
0.69 of 1450. So
0.69*1450 = 1000.5
LCL = 522, UCL = 1000.5
Second question:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of
.
The margin of error is:

The project manager believes that p will turn out to be approximately 0.11.
This means that 
95% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
The project manager wants to estimate the proportion to within 0.03
This means that the sample size needed is given by n, and n is found when M = 0.03. So






Rounding up
A sample size no smaller than 418 is needed.
The first month in which the board will see the cumulative total number of candy bars sold in Manila exceeded the cumulative total in Seoul is of:
3rd month.
<h3>What are linear functions?</h3>
The slope-intercept definition of a linear function is presented as follows:
y = mx + b.
In which the coefficients are defined as follows:
- m is the slope, representing the rate of change.
- b is the y-intercept, representing the initial value.
For the functions in this problem, the slope and the intercept are given as follows:
- Intercept: amount sold by the end of the first month.
Taking the end of the first month as a parameter, the functions are defined as follows:
- Seoul: S(m) = 40 + 60(m - 1).
- Manila: M(m) = 20 + 80(m - 1).
Then Manila exceeds Seoul when:
M(m) > S(m)
20 + 80m - 80 > 40 + 60m - 60
20m > 40
m > 2.
2.1 for example is in the 3rd month, hence the 3rd month is the correct answer.
