An industrial plant claims to discharge no more than 1000 gallons of wastewater per hour, on the average, into a neighboring lake. An environmental action group decides to monitor the plant, in case this limit is being exceeded. A random sample of four hours is selected over a period of a week. The observations (gallons of wastewater discharged per hour) are 1234, 1543, 2453, 2010 . Complete parts a through d below.

An industrial plant claims to discharge no more than 1000 gallons of wastewater per hour, on the average, into a neighboring lake. An environmental action group decides to monitor the plant, in case this limit is being exceeded. A random sample of 42 hours is selected over a period of a month. The data are unimodal and roughly symmetric. R 1123, s- 688, and Standard Error 106.161 (a) Using StatCrunch, the p-value (3 decimal places) (b) Are the conditions met...

By a local policy, any industrial plant cannot discharge more than 500 gallons of waste water into the local lake in any given hour. A researcher randomly sampled 100 hours when the plant is in production, and record the gallons of waste water discharged. Below is the statistical software print out of the summary statistics: Variable n mean SD Waste 100 512 50 (2.1) The researcher is interested in whether the plant violated the local policy. State the null and...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
