Polyelectrolytes are typically used to separate oil and water in industrial applications. The separation process is dependent on controlling the pH. Fifteen {15) pH readings of wastewater following these processes were recorded. Is it reasonable to model these data using a normal distribution? 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 10.0 10.5 7.6 |11.4 11.4 10.0 0 Yes, it passes the "fat pencil\" test. Therefore, a normal distribution is a reasonable model. 0 No, it does not pass the "fat pencil\" test.
