A group project in an intro stats project looks at the cost of gasoline. Students recorded the cost per gallon at a nearby gas station over a period of 10 weeks and want to make a time plot. What variable goes on the horizontal axis?
Choose the correct answer below.
Time (week 1 - Week 10)
Day of the week the cost was recorded (Sun - Sat)
Cost per gallon

Time (week 1 - week 10)

Step-by-step explanation:

Given

Measure of cost of gasoline over a period of time

Required

Determine what variable belongs to the horizontal axis

To answer this question, I'll re-echo the given parameters again

Measure of cost of gasoline over a period of time

This can be rephrased to be

Measure of cost of gasoline with respect to time

This means that the cost of gasoline is a function of time (10 weeks, to be precise).

Hence;

Cost will be on the vertical axis

Time will be on the horizontal axis

Conclusively,

The first option answers the question
