###### Question details

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.

i) State the Coefficient of Determination for this data set and interpret this value in the context of the issue under consideration.

ii) What does the “t statistic” of 3.992 (relating to Resting_Rate) and the associated p value tell us in the context of the data?

iii) Using the regression equation from part (b), predict the maximum oxygen consumption rate of a male athlete with resting oxygen consumption rate of 2.0 mL/kg/min.
