If the data collected is considered as ordered pairs, what is the range of the data?
{10, 12, 20, 24}
18 ≤ x ≤ 50
{18, 23, 26, 50}
D) all real numbers
The range of the data refers to the set of all possible outputs or values of the second component of each ordered pair. In this case, the second component represents the number of times per month they ate fast food.
From the given data, the range of the data is {10, 12, 20, 24}.
It is not {18, 23, 26, 50} because those are the ages of the individuals, not the number of times they ate fast food.
It is also not 18 ≤ x ≤ 50 because this represents an inequality, not a set of values.
And it is not "all real numbers" because the data is limited to specific values given in the survey.
