Answer:
The graph has a correlation coefficient, r, closest to 0.957 is graph C (option C)
Step-by-step explanation:
Given:
4 graphs showing the relationship between quantities
To find:
the graph that has a correlation r closest to 0.957
To determine the correct graph, we will check each of the options:
For the correlation to be close to 0.957, it has to be close to 1. Correlation with points close to 1 are closely packed showing a straight line
a) The dots are increasing but they are scattered.
b) The dots are decreasing. r is positive so the dots shouldn't be decreasing.
c) The dots are increasing and they are closely aligned towards to straight line
d) The dots are decreasing and they are scattered.
Hence, the correct graph is option C
