Considering the margin of error of a confidence interval, it is found that the correct option is:
It would be half as wide.
<h3>What is the margin of error of a confidence interval?</h3>
It is modeled by:
In which:
- s is the standard deviation.
From this, we get that the margin of error is inversely proportional to the square root of the sample size. Then, multiplying the sample size by 4, when it changes from 50 to 200, cuts the margin of error in half, making the interval half as wide.

Answer:
look below
Step-by-step explanation:
The mean of Restaurant A is 17.3
The mean of Restaurant B is 15.8
The median of Restaurant A is 18
The median of Restaurant B is 15
The mode of Restaurant A is 18
The mode of Restaurant B is 15
The range of Restaurant A and B is 10
The line plots are the same because they have the same range
The line plots are different because they have different means, medians, and modes.
