a. According to the graph, define the input and output variables, including units. b. Explain the trend and association in context of the graph. For example, does the graph have a positive, negative or no trend and is the association strong, moderate or weak? Be sure to write your answer in context. C. Use the equation of the regression line to interpret the rate of change, including units. d. Use the equation of the regression line to calculate the predicted pulse rate for a person who weighs 145 pounds. Do not round your answer.
