An environmental scientist is studying the rate of absorption of a certain chemical into skin. She places differing volumes of the chemical on different pieces of skin and allows the skin to remain in contact with the chemical for varying lengths of time. She then measures the volume of chemical absorbed into each piece of skin. She obtains the results shown in the following table.

The scientist plots the percent absorbed against both volume and time, as shown in the following figure. She calculates the correlation between volume and absorption and obtains r = 0.988. She concludes that increasing the volume of the chemical causes the percentage absorbed to increase. She then calculates the correlation
between time and absorption, obtaining r = 0.987. She concludes that increasing the time that the skin is in contact with the chemical causes the percentage absorbed to increase as well. Are these conclusions justified?
