Sagot :
I have attached a drawing of the line plot.
Here are the data points from the line plot:
[tex]\{27,\ 28,\ 28,\ 29,\ 29,\ 29,\ 30,\ 30,\ 30,\ 31,\ 31,\ 31,\ 33,\ 34\}[/tex]
Choosing a measure of central tendency:
Use the mode if there is one number which appears as a vast majority towards the center.
Use the median if there are a lot of outliers. (numbers far away from the rest)
Use the mean otherswise.
In this case, we would use the mean, because there is no number which appears as a vast majority or any outliers.
The mean is calculated by adding up the numbers and dividing by how many numbers you have.
When we add up our numbers, we get 420.
We have 14 numbers.
420 divided by 14 is [tex]\boxed{30}[/tex].
