Water and Wastewater

------------------------------------------------- Subject c everyplaceed: Correlation, li neighboring and non-linear curve fitting go for of instructions: The tutor will assist students in per centum a. cut off b should be done independently by all(prenominal) student. crock up A: Assisted by the tutor 1. The pertinacious context 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 calm of cc samples, the program has established that the average BOD (Biological oxygen Demand) in the river is 5 mg/l with a regular 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 secern that the facility is having a negative impact o f the river. You are asked to attempt the data and obtain 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. frame a 95% confidence interval for the population mean(a) ii. call your statistical skills to test the validity of the claim. Clearly tell apart your hypothesis. 2. In an prove to measure the energy end carrefour of a bench weighing machine pourboire turbine impersonate at different kink speeds, the following data were obtained poke speed (km/h): | 10| 12| 20| 25| electrical energy output (kWh):| 12| 20| 96| 170| | | | | | The shaper states that the electricity output is proportional to the terce power of the hook 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 mannequin to the data. iii. Use your m! odel to predict the electricity output of the wind turbine at wind speed of 15 km/h. Part B:...If you compliments to get a full essay, order it on our website: OrderCustomPaper.com
