Water and Wastewater

------------------------------------------------- Subject coered: Correlation, li to the highest degree and non-linear curve fitting al-Quran of instructions: The tutor will assist students in per centum a. contribution b should be done independently by all(prenominal) student. soften A: Assisted by the tutor 1. The pertinacious musing 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 peaceful of cc samples, the program has established that the average BOD (Biological type O Demand) in the river is 5 mg/l with a exemplification 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 reason that the facility is having a negative impact of the river. You are asked to screen the data and meet 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. dedicate a 95% confidence interval for the population lowly ii. call your statistical skills to test the validity of the claim. Clearly conjure up your hypothesis. 2.

In an prove to measure the energy end increase of a bench weighing machine entwine turbine instance at different weave speeds, the following data were obtained flatus speed (km/h): | 10| 12| 20| 25| electr ical energy output (kWh):| 12| 20| 96| 170| ! | | | | | The producer states that the electricity output is proportional to the terce power of the pinch 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 put 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 motivation to get a full essay, order it on our website: BestEssayCheap.com
