A study was performed on a method of purifying nuclear fuel waste. The process involves oxidation in molten salt and tends to produce oxygen bubbles with a rising velocity. To monitor the process, the researchers collected data on bubble velocity (measured in meters per second) for a random sample of 18 photographic bubble images. These data (simulated) are reproduced in the accompanying table. When oxygen is inserted into the molten salt at a rate (called the sparging rate) of 3.33 X 10 6, the researchers discovered that the true mean bubble rising velocity is p. = 0.338.
