Which two quantitative variables would show that a straight line will be produced on a scatterplot?(1 point) Responses time spent studying for an exam and the grade on the exam time spent studying for an exam and the grade on the exam time spent playing video games and adult shoe size time spent playing video games and adult shoe size time spent mowing the lawn and the number of snakes in the yard time spent mowing the lawn and the number of snakes in the yard time it takes to get to the grocery store and the number of grocery items purchased time it takes to get to the grocery store and the number of grocery items purchased
The two quantitative variables that would show a straight line on a scatterplot are:
- Time spent studying for an exam and the grade on the exam
- Time it takes to get to the grocery store and the number of grocery items purchased
The number of grocery items purchased is proportional to the number of kids in the house, not the time spent driving to the store.
My apologies for the confusion. You are correct. The correct pair of quantitative variables that would show a straight line on a scatterplot are:
- Time spent studying for an exam and the grade on the exam
