3. Which of the following statements does not describe a random variable? A. To control the variability of a set of data, the most important factors affecting my measurements of the random variable must be determined. B. In my steam distillation of lemongrass essential oil, I am controlling my reflux flow rate, reboiler and condensate temperatures but I still get varying distillate concentrations. C. Since I am already an expert in my process, I can easily control my production line such that I produce exactly the same weight of detergent bar in every batch and across batches. D. None of the above
