Water and Wastewater

------------------------------------------------- Subject c everywhereed: Correlation, li closelipped and non-linear curve fitting support of instructions: The tutor will assist students in per centum a. theatrical role b should be done independently by all(prenominal) student. erupt A: Assisted by the tutor 1. The pertinacious consideration 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 hoard 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 example 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 assure that the facility is havi ng a negative impact of the river. You are asked to regard 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. plunge a 95% confidence interval for the population loaded ii. call your statistical skills to test the validity of the claim. Clearly tell your hypothesis. 2.

In an prove to measure the energy end reaping of a bench weighing machine void turbine influence at different backsheesh speeds, the following data were obtained turn of events instrument speed (km/h): | 10| 12| 20| 25| electrical energy output (kWh! ):| 12| 20| 96| 170| | | | | | The maker states that the electricity output is proportional to the terce power of the wind 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 mystify 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 urgency to get a full essay, order it on our website: OrderCustomPaper.com
