The Turbine Oil Oxidation Test (TOST) and the Rotating Bomb Oxidation Test (RBOT) are two different procedures for evaluating the oxidation stability of steam turbine oils. An article reported the accompanying observations on x = TOST time (hr) and y = RBOT time (min) for 12 oil specimens.

(Round your answer to four decimal places.) Interpret the value of the sample correlation coefficient. O The value of r indicates that there is a weak, positive linear relationship between TOST and RBOT. O The value of r indicates that there is a strong, negative linear relationship between TOST and RBOT. O The value of r indicates that there is a weak, negative linear relationship between TOST and RBOT. O The value of r indicates that there is a strong, positive linear relationship between TOST and RBOT. (b) How would the value of r be affected if we had let x- RBOT time and y = TOST time? O The value of r would increase. O The value of r would remain the same. O The value of r would be multiplied by -1. O The value of r would decrease. (c) How would the value of r be affected if RBOT time were expressed in hours? O The value of r would increase. O The value of r would decrease. O The value of r would be multiplied by -1. O The value of r would remain the same.
