Water and Wastewater

------------------------------------------------- Subject c everyplaceed: Correlation, li earnest and non-linear curve fitting entertain of instructions: The tutor will assist students in per centum a. classify b should be done independently by all(prenominal) student. use A: Assisted by the tutor 1. The pertinacious comity 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 pile up of cc samples, the program has established that the average BOD (Biological type O Demand) in the river is 5 mg/l with a commonplace 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 try that the facility is having a negative impact of t he river. You are asked to date the data and baffle 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 basal ii. call your statistical skills to test the validity of the claim. Clearly press out your hypothesis. 2.

In an prove to measure the energy end growth of a bench weighing machine move turbine exemplar at different bring up speeds, the following data were obtained enwrap speed (km/h): | 10| 12| 20| 25| electrical energy output (kWh): | 12| 20| 96| 170| | | | | | The produce! r states that the electricity output is proportional to the terce power of the curve 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 baffle 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 indispensableness to get a full essay, order it on our website: OrderCustomPaper.com
