Question

the scatterplot illustrates the relationship between two quantitative variables: the amount of an active ingredient in a medicine and the level of pain relief (on a scale of 1 to 10). the relationship in the scatterplot is weak positive and linear. positive and nonlinear. negative and moderately strong. active ingredient and allergy relief

Explanation:

• A positive relationship in a scatter - plot means that as the value of one variable (active ingredient) increases, the value of the other variable (relief score) also tends to increase.
• A linear relationship would have the points roughly following a straight - line pattern. Here, the points do not follow a straight - line pattern.
• A weak relationship would have the points more spread out with no clear trend. But here, there is a trend of increase.
• A negative relationship would have one variable increasing as the other decreases. That is not the case here.

Answer:

positive and nonlinear.
