What is the correlation coefficient for the data shown in the table?
0
1
4
5

Answer:
r = 1
Step-by-step explanation:
The two variables are directly proportional, that is, there is function with form y = kx that relates the variables. We can see from the table, that the equation y = x perfectly match both variables (k = 1). Given that the slope is positive and the match is perfect, the correlation coefficient is one.
