1. Time spent studying for an exam and the grade on the exam.
2. Time it takes to get to the grocery store and the number of grocery items purchased.
which one?
The correct answer is: Time spent studying for an exam and the grade on the exam.
The two quantitative variables that would show a straight line on a scatterplot are:
1. Time spent studying for an exam and the grade on the exam: In this scenario, as the amount of time a person spends studying for an exam increases, their grade on the exam would also tend to increase. This positive correlation between time spent studying and the exam grade would result in a straight-line relationship on a scatterplot.
2. Time it takes to get to the grocery store and the number of grocery items purchased: Here, as the time it takes to reach the grocery store increases, the number of grocery items purchased would generally increase as well. This positive relationship would also produce a straight-line pattern on the scatterplot.
To determine if a scatterplot will produce a straight line, it is important to consider the relationship between the variables. If there is a consistent increase or decrease in one variable corresponding to changes in the other variable, it indicates a linear relationship and would result in a straight line on the scatterplot.
