Question

which statement is true about the association of the data sets?
both sets have positive correlation.
both sets have weak linear association.
both sets have negative correlation.
there is no correlation between the sets.

Explanation:

Step1: Analyze Correlation Direction

For a scatter plot, positive correlation means as \( x \) increases, \( y \) increases. In both graphs, as days of sunlight (\( x \)) increase, the other variable (\( y \)) increases.

Step2: Evaluate Other Options

• Weak linear association: Points in both are somewhat clustered along a line, not weak.
• Negative correlation: \( y \) doesn't decrease with \( x \), so false.
• No correlation: There is a trend, so false.

Answer:

Both sets have positive correlation.
