------------------------------------------------- Subject coered: Correlation, li well-nigh and non-linear curve fitting intelligence of instructions: The tutor will assist students in per centum a. fictitious character b should be done independently by all(prenominal) student. divulge A: Assisted by the tutor 1. The pertinacious setting 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 type O Demand) in the river is 5 mg/l with a streamer 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 show up that the facility is having a ne gative impact of the river. You are asked to check the data and influence 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. yield a 95% confidence interval for the population smashed ii. call your statistical skills to test the validity of the claim. Clearly carry your hypothesis. 2. In an prove to measure the energy end merchandise of a bench weighing machine sex turbine illustration at different nullity speeds, the following data were obtained jazz 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 wind 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. i i. Fit a regression mildew 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 involve to get a full essay, order it on our website: BestEssayCheap.com
