Answer:
B. Te procedure for constructing the confidence interval is robust. The larger the sample size, the more resistance the mean. Therefore, the confidence interval is more robust.
Step-by-step explanation:
Misentered data illustrates the concept that if the sample size is larger it will be more resistance to mean. This means confidence interval is more robust. In statistics, robust is a modification of confidence interval. It refers to strength of statistical model. Robust statistics is resistant to errors in statistical model.
We conclude that the profit if the company produces 10 units is 1,040 dollars.

How to find the profit?</h3>
The profit is defined as the difference between the revenue and the costs.
In this case, we know that the revenue and costs are defined by:
R(x) = 200x - 5x^2
C(x) = 360 + 6x
Then the profit equation is:
P(x) = R(x) - C(x).
P(x) = 200x - 5x^2 - (360 + 6x)
P(x) = -5x^2 + 194x - 360
Now we want to find the profit when x = 10, then we will get:
p(10) = -5*10^2 + 194*10 - 360 = 1,040
We conclude that the profit if the company produces 10 units is 1,040 dollars.
