Answer:

A = strong negative correlation

B = positive correlation

C = very weak or no correlation

Step-by-step explanation:

Scatter plot A:

A clear linear trend line could be observed having a negative slope ; the nature of the slope gives the nature of the correlation (positive or negative). Since the slope is negative then we have a negative correlation. The linear trend line is almost straight with only few points marginally missing the best fit line. Hence. We can conclude to have a strong negative correlation.

Scatter plot B :

Has a positive slope, and hence a positive correlation. The best fit line miss a few points but the linear trend of the plot is still observable. Hence, we can conclude to having a fairly strong positive correlation.

Scatter plot C :

From the graph, no linear trend can be observed and hence it is fit to say that no correlation exists between the points.
