A wastewater treatment plant serves a city with a total population of 50000. The total service area for the treatment plant is 100 km2. The wastewater flow is 300 L/cap.d. During the wet weather conditions, the expected infiltration/inflow for the city is 3800 L/Ha.d.   Estimate the peak flow for this treatment plant (m3/d).

Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
