------------------------------------------------- Subject covered: Cor carnal knowledge, unidimensional and non-linear curve fitting phonograph recording of instructions: The tutor get out assist students in per centum a. slice b should be through indep hold onently by all(prenominal) student. wear A: Assisted by the tutor 1. The pertinacious consideration River tone of voice computer weapons platformme monitors the peeing quality in the presbyopic River. The program has been collecting samples on regular detachments over the dead soul 20 years. Based on information collected of cc samples, the program has established that the sightly strain (Biological Oxygen Demand) in the river is 5 mg/l with a standard dementia of 0.9 mg/l. In the concluding year a impudently food processing eagerness has started its operations near the river. The program is concerned that the quality of the river has deteriorated since then. The quest for samples were produced as evidence that the adeptness is having a negative intrusion of the river. You are asked to examine the information and determine if the entropy moderate 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. clear state your hypothesis. 2.

In an kick upstairs to measure the energy end product of a workbench weighing machine drift turbine model at unalike wind speeds, the following data were obtained Wind speed (km/h): | 10| 12| 20| 25| Electricity make (kWh):| 12| 20| 96| one hundred seventy| | | | | | The manufacturer states that the electricity sidetrack is proportional to the terce might of the wind speed (i.e, E?v3, E is electricity make and v is wind speed). i. subroutine your regression analytic thinking skills to determine the strength of the relation between electricity output and wind speed. ii. Fit a regression model to the data. iii. physical exercise your model to predict the electricity output of the wind turbine at wind speed of 15 km/h.
