Answer 1

As the baby gains weight, computer prices tend to increase.

Step-by-step explanation:

The correlation coefficient of 0.87 indicates a strong positive correlation between a baby's weight and the price of a computer.

This means that as the baby's weight increases, computer prices also tend to increase, so option A is correct.

It is important to note that a correlation does not necessarily imply causation. In this case, the correlation coefficient indicates a relationship between the two variables, but it does not indicate that the baby's weight gain causes the price of a computer to increase or vice versa.
