3) Obtain the expected frequency for each cell (each cell worth
0.25 point; total 1.5 points)
4) Construct a summary table in which, for each cell, you report
the observed and expected frequencies, subtract the expected from
the observed frequency, square this difference, divide by the
expected frequency, and sum these quotients to obtain the
Chi-square value (each cell worth 0.2 point; total 3.8
points)
5) Find the degrees of freedom (0.7 point)
6) Compare the calculated Chi-square value with the critical
Chi-square value from Table F, Appendix C. Draw Conclusions about
H0. If the calculated one is larger than the critical one, we
reject H0. Otherwise, we accept H0.
3) Obtain the expected frequency for each cell (each cell worth 0.25 point; total 1.5 points)...

Before beginning the design of an apparatus meeting this standard, the designer shall review the discussion on the limitations and accuracy, Section 13, discussions of the energy flows in a hot box, Annex A2, the metering box wall loss flow, Annex A3, and flanking loss, Annex...
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...
