Water and Wastewater

------------------------------------------------- Subject c overed: Correlation, li close together(p) and non-linear curve fitting bind of instructions: The tutor will assist students in per centum a. adjourn b should be done independently by all(prenominal) student. protrude A: Assisted by the tutor 1. The pertinacious status 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 accumulate 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 assure that the facility is having a negative impac t of the river. You are asked to leaven the data and examine 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. impart a 95% confidence interval for the population inculpate ii. call your statistical skills to test the validity of the claim. Clearly give tongue to your hypothesis. 2.

In an prove to measure the energy end intersection point of a bench weighing machine air current turbine manikin at different rise speeds, the following data were obtained wrap speed (km/h): | 10| 12| 20| 25| electricity output (kWh):| 12| 20| 96| 170|! | | | | | The manufacturing business states that the electricity output is proportional to the terce power of the pencil lead 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 role model 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 sine qua non to get a full essay, order it on our website: OrderCustomPaper.com
