Water and Wastewater

------------------------------------------------- Subject coered: Correlation, li salutary and non-linear curve fitting ledger of instructions: The tutor will assist students in per centum a. fail b should be done independently by all(prenominal) student. component A: Assisted by the tutor 1. The pertinacious rumination River Quality computer programme monitors the water quality in the Long River. The program has been collecting samples on regular intervals over the departed 20 years. Based on information unruffled of cc samples, the program has established that the average BOD (Biological atomic number 8 Demand) in the river is 5 mg/l with a sample aberration of 0.9 mg/l. In the last year a impudently food processing readiness has started its operations near the river. The program is concerned that the quality of the river has deteriorated since then. The chase samples were produced as record that the facility is having a negative impac t of the river. You are asked to pick up the data and larn if the data support the claim. Sample #| 1| 2| 3| 4| 5| 6| 7| 8| 9| 10| BOD (mg/l)| 3.8| 5.6| 5.3| 4.4| 5.1| 6| 4.8| 6.5| 4.3| 5.3| i. stool a 95% confidence interval for the population entail ii. call your statistical skills to test the validity of the claim. Clearly deposit your hypothesis. 2.

In an prove to measure the energy end merchandise of a bench weighing machine enlace turbine stupefy at different perfume speeds, the following data were obtained principal speed (km/h): | 10| 12| 20| 25| electricity output (kWh):| 12| 20| 96| 170| | | | | | The producer! states that the electricity output is proportional to the terce power of the wrap up speed (i.e, E?v3, E is electricity output and v is wind speed). i. Use your regression analytic thinking skills to determine the strength of the relation between electricity output and wind speed. ii. Fit a regression manakin to the data. iii. Use your model to predict the electricity output of the wind turbine at wind speed of 15 km/h. Part B:...If you indirect request to get a full essay, order it on our website: OrderCustomPaper.com
