The correlation coefficient for the cost and size of storage containers is 0.52. how are the cost and container size related

There is a positive correlation between both variables.

Step-by-step explanation:

That is to say, the relation between the cost and the size of the storage containers is growing.

As the size of the container increases the cost also increases.

The closer the correlation coefficient is to 1, the stronger is the positive relationship between the variables, in this case r = 0.52, so it could be concluded that the relationship between the variables is a medium  positive correlation
