Final Answer:
The article "Reliability of Domestic Biofilm Reactors" (J. of Envir. Engr., 1995: 785-790) suggest that substrate concentration (mg/cm3) of influent to a reactor is normally distributed with = 0.3 and σ= 0.06.
Step-by-step explanation:
The statement indicates that the influent substrate concentration in a reactor follows a normal distribution. In statistics, a normal distribution is characterized by two parameters: the mean (μ) and the standard deviation (σ). In this scenario, the mean (μ) of the substrate concentration in the influent is given as 0.3 mg/cm3, representing the average or central tendency of this distribution. Meanwhile, the standard deviation (σ) is specified as 0.06 mg/cm3, denoting the measure of dispersion or spread of the data around the mean.
This information is crucial in understanding the behavior of substrate concentrations entering the reactor. Knowing that the data follows a normal distribution allows for the application of statistical tools and methods that rely on this distribution pattern. It helps in predicting probabilities associated with different concentration levels, assessing the likelihood of certain outcomes, and making informed decisions about reactor performance or treatment efficiency based on the influent substrate concentrations.
Correct answer: "normally distributed with = 0.3 and σ= 0.06."
