Researchers investigated the capacity for oxygen consumption in athletes, with the objective being to see whether the maximum possible oxygen consumption rate (Max_Rate) of an individual could reliably be predicted from the resting oxygen consumption rate (Resting_Rate). Resting_Rate (mL/kg/min) and Max_Rate (mL/kg/min) were determined for 25 male athletes and the data analysed below. Use the plot that follows and the related computer output from a simple linear regression to answer the following questions.
(a) Using the scatter plot describe the relationship between Max_Rate and Resting_Rate.
(b) Write down the regression equation that describes the relationship between Max_Rate and Resting_Rate.
(c) Interpret the coefficient of Resting_Rate in the regression equation in the context of the data. [2 marks]
