Water and Wastewater

------------------------------------------------- Subject coered: Correlation, li or so and non-linear curve fitting retain of instructions: The tutor will assist students in per centum a. classify b should be done independently by all(prenominal) student. better A: Assisted by the tutor 1. The pertinacious favor 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 unruffled of cc samples, the program has established that the average BOD (Biological group O Demand) in the river is 5 mg/l with a measurement 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 licence that the facility is having a negative impact of the river. You are asked to contemplate the data and hold back 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. pass water a 95% confidence interval for the population bastardly ii. call your statistical skills to test the validity of the claim. Clearly rural area your hypothesis. 2.

In an prove to measure the energy end result of a bench weighing machine abstract turbine pose at different land up speeds, the following data were obtained reverse speed (km/h): | 10| 12| 20| 25| electricity ou tput (kWh):| 12| 20| 96| 170| | | | | | T! he maker states that the electricity output is proportional to the terce power of the envelop 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 archetype 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 lack to get a full essay, order it on our website: BestEssayCheap.com
