An correlation is calculated to explore the linear relationship between the weight of a newborn baby (in gram) and the number of cigarettes smoked by the mother. Which of the following statements is correct? The correlation will change if we convert either the birth weight from grams to ounces or the number of cigarettes smoked to packs of cigarettes smoked. The correlation will not change if we convert the birth weight from grams to ounces and the number of cigarettes smoked to packs of cigarettes smoked. Suppose the reported correlation is -1.2. It implies birth weight appears to decline with the amount of cigarettes smoked. Suppose the reported correlation is -0.7. It implies heavier babies are related to more cigarette smoking.

From the group of all answers given above, it goes to show that the correct statement that was correct was that on "Suppose the reported correlation is -1.2. It implies birth weight appears to decline with the amount of cigarettes smoked."

This simply means that, the decline of the baby's weight towards negative has a direct effect due to the increase in the number of cigarettes smoked by the babys' mothers.
