Question

the scatterplot illustrates the relationship between two quantitative variables: the number of seeds planted per square foot and the yield of the crop (in pounds per square foot).
which of the following is an accurate description of the scatterplot?
the more seeds that are planted per square foot, the smaller the expected yield of the crop.
the more seeds that are planted per square foot, the larger the expected yield of the crop.
the expected yield of a crop is high whenever the number of seeds planted per square foot is small or large. a larger yield is expected when the number of seeds per square foot is around 60.
the expected yield of a crop is low whenever the number of seeds planted per square foot is small or large. a larger yield is expected when the number of seeds per square foot is around 60.

Explanation:

Looking at the scatter - plot, when the number of seeds per square foot is small (e.g., around 20), the yield is low. As the number of seeds increases to around 60, the yield increases. But when the number of seeds per square foot is large (e.g., above 70), the yield decreases. So, the expected yield of a crop is low whenever the number of seeds planted per square foot is small or large. A larger yield is expected when the number of seeds per square foot is around 60.

Answer:

The expected yield of a crop is low whenever the number of seeds planted per square foot is small or large. A larger yield is expected when the number of seeds per square foot is around 60.
