The answers to the various part as well as its reasons are given below
<h3 /><h3>Part A:</h3>- The x-intercepts shows a zero profit.
- The maximum value of the graph tells or depict the maximum profit.
- The function is one that goes up or increases upward until it reach the vertex and then it falls or decreases after it.
- This implies that the profit goes up as it reaches the peak at the vertex and it goes down after the vertex up until it gets to zero.
- The profits are negative as seen on the left of the first zero and on the right of the second zero.
An approximate average rate of change of the graph from x = 3 to x = 5, shows the reduction in profit from 3 to 5.
<h3>Part C:</h3>Based on the above, the domain is one that is held back or constrained by x = 0 .
We are compelled at x = 6 due to the fact that we have to maneuver a negative profit.

Answer:
The 95% confidence interval estimate of the population proportion of managers who have caught salespeople cheating on an expense report is (0.5116, 0.6484).
Step-by-step explanation:
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 .
In the survey on 200 managers, 58% of the managers have caught salespeople cheating on an expense report.
This means that
95% confidence level
So , z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:
The upper limit of this interval is:
The 95% confidence interval estimate of the population proportion of managers who have caught salespeople cheating on an expense report is (0.5116, 0.6484).
