Question

1. Write a short report on Sampling and how a Sample Size could be determined both statistically and non-statistically 2. The class captain Mr. Lucas Adiambra presented a paper entitled "Challenges in Academic Research" during the RCEES 20 International Conference on Engineering in Sunyani from the 11* - 13* December, 2019. The Conference proceedings were edited by Prof. James Dugan and Dr. Godwin Nyamekye which was published as a book on January 20, 2020 by KNUST Press. The title of the book is "Academic Research in the 21" Century" and his paper can be found in pages 201 - 210. He was later joined by a friend. Mr. Charles Yambra to publish the same article in a Joumal of Environment and Natural Resources Management (JENRM), the 12 Series in the third volume, pages 234 to 241. The article was so interesting that, one of their Lecturers (Dr. Francis Fameye) encouraged them to publish the article as a chapter of a book he edited entitled "Research in Ghana" printed by Elsevier, London from pages 35 to 42. He finally met another friend (Mr. Proper Awuni) who had also worked on similar information and therefore they decided to combine the work and publish it into a book with the same title in the same year. The book was finally published by the KNUST Press in Kumasi. From the information above in question two, provide the reference lists for all the scenarios.
