Expert Solution
Step 1

The objective is to interpret the correlation coefficient, R (and -1≤R≤1) from the provided graph. The correlation coefficient may be defined as the numerical value that measures the extent of the linear relationship between two variables, i.e., the variable "protein content (in mg mL-1)" that is defined on the x-axis, and the variable "absorbance" that is defined on the y-axis.
