Continuous random variables that can assume values at all points on an interval of values, with no breaks between possible values, are quite common. Examples include:
A) profit per dollar of sales
B) cost per credit taken by graduate students
C) the average time it takes to assemble a car, or write a test
D) height
E) all of these

Question

Quizplus · Accepted Answer

All of these examples involve continuous random variables that can take on any value within a given interval without any breaks between possible values. Profit per dollar of sales and cost per credit taken by graduate students can vary continuously and take on any value within a range. The average time it takes to assemble a car or write a test can also vary continuously and take on any value within a range. Height is also a continuous variable that can vary continuously and take on any value within a range.
