A botanist created a linear model to predict plant height from soil acidity (pH level) for a certain type of plant. The slope of
the model was 2.5 centimeters per pH level, the standard deviation of the sample of plant heights was 4 centimeters, and the standard deviation of the soil acidities was 1 pH level. What is the value of the correlation coefficient? A 0.015 (B) 0.10 c. .25 d. 0.625 E 1.60
