2. which of the following graphs below shows a strong positive correlation? a. graph 1 b. graph 2 c. graph 3

Explanation:

Step1: Recall positive - correlation concept

In a positive - correlation, as the value of $x$ increases, the value of $y$ also increases.

Step2: Recall strong - correlation concept

In a strong correlation, the data points are closely clustered around a line.

Step3: Analyze each graph

Graph 1: The data points are closely clustered and as $x$ increases, $y$ increases. Graph 2: The data points are more spread out and the upward trend is less clear. Graph 3: There is no clear upward or downward trend.

Answer:

a. Graph 1
