Final answer:
There is a positive correlation between the number of doughnuts Homer eats and his weight. If Homer wants to lose weight, he should eat fewer doughnuts. On a scatterplot, an increase on the y-axis would lead to an increase on the x-axis.
Step-by-step explanation:
In the given question, we are looking at the correlation between the number of doughnuts Homer eats and his weight. The question asks for the type of correlation and the steps Homer should take if he wants to lose weight.
Based on the information provided, there is a positive correlation between the number of doughnuts Homer eats and his weight. This means that as the number of doughnuts increases, his weight also increases. Therefore, if Homer wants to lose weight, he should eat fewer doughnuts since a decrease in consumption will likely lead to a decrease in weight.
If Homer graphed this relationship on a scatterplot, an increase on the y-axis (vertical axis) would lead to an increase on the x-axis (horizontal axis). As the number of doughnuts consumed (x-axis) increases, his weight (y-axis) would also increase.
