Problem

Interpret the moderate positive scatter pattern between hours of sleep and reaction-time score, where a higher score means a faster reaction. State the direction, strength, contextual tendency, and causation limitation.

Source contextual scatterplot: A scatter plot of hours of sleep and reaction-time score, where higher means faster, is described as moderate positive. Which statement correctly interprets this pattern? The plotted variables and described pattern are shown without a contextual or causal conclusion.

Hours of sleep and reaction-time score have no association because higher scores cannot represent faster reactions.

More sleep causes faster reactions because the association is moderate and positive.

More sleep tends to accompany lower reaction-time scores, meaning slower reactions, because the association is negative.

More sleep tends to accompany higher reaction-time scores, meaning faster reactions; this is a moderate positive association but does not establish causation.
