Emma is part of a team developing a new water softening agent. After gathering data about the softening agent's concentration in a volume of water over time, Emma recognizes this is an exponential decay situation and uses her computer to develop a model of the curve of best fit. The model of the curve of best fit for Emma's data has a correlation coefficient of r = -0.28. Which statement about Emma's model is true?

Which statement about Emma's model is true? The model of the curve of best fit for Emma's data has a correlation coefficient of r = -0.28 Predictions made using Emma's model are reliable because r is closer to 0 than -1. Predictions made using Emma's model are unreliable because r is not positive. Predictions made using Emma's model are unreliable because r is closer to 0 than -1. Predictions made using Emma's model are reliable because r is not positive.
