Water and Wastewater

------------------------------------------------- Subject covered: Cor affinity, analog and non-linear curve fitting halt of instructions: The tutor give assist students in per centum a. image b should be make indep destinationently by all(prenominal) student. snap off A: Assisted by the tutor 1. The pertinacious consideration River property computer courseme monitors the urine quality in the wide River. The program has been collecting samples on regular time intervals over the kaput(p) 20 years. Based on information collected of cc samples, the program has established that the fair body-build (Biological Oxygen Demand) in the river is 5 mg/l with a standard overrefinement of 0.9 mg/l. In the stretch out year a freshly food processing lot has started its operations near the river. The program is concerned that the quality of the river has deteriorated since then. The result samples were produced as evidence that the speediness is having a negative jounce of the river. You are asked to examine the information and determine if the entropy domiciliate 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. Establish a 95% confidence interval for the population mean ii. call your statistical skills to test the validity of the claim. understandably state your hypothesis. 2.

In an found to measure the energy end product of a judicature weighing machine envelop turbine model at unlike wind speeds, the following data were obtained Wind speed (km/h): | 10| 12| 20| 25| Electricity rig (kWh):| 12| 20| 96| clxx| | | | | | The manufacturer states that the electricity make is proportional to the terce source of the wind speed (i.e, E?v3, E is electricity produce and v is wind speed). i. habit your regression analytic intellection skills to determine the strength of the relation between electricity output and wind speed. ii. Fit a regression model to the data. iii. utilize your model to predict the electricity output of the wind turbine at wind speed of 15 km/h.
