(i) It was conducted at the Hawthorne plant of the Western Electric Company

Hawthorne Experiments: Statement Analysis
The question asks to identify the statements that are not true regarding the Hawthorne experiments. Let's analyze each statement:
- Statement (i): It was conducted at the Hawthorne plant of the Western Electric Company.
- Analysis: This statement is true. The Hawthorne experiments are famously named after the Hawthorne Works of the Western Electric Company in Cicero, Illinois.
- Statement (ii): It was done between 1934-40.
- Analysis: This statement is not true. The principal Hawthorne studies were conducted over a longer period, mainly from 1924 to 1932. While some follow-up research or analysis might have occurred later, the core experimental phase concluded earlier than 1934.
- Statement (iii): It was sponsored by National Research council of the National Academy of Science.
- Analysis: This statement is true. The initial phases of the Hawthorne studies, particularly the Relay Assembly Test Room experiments, were supported and sponsored by the National Research Council (NRC) of the National Academy of Sciences.
- Statement (iv): Hawthrone plant had nearly 59,000 employees.
- Analysis: This statement is not true. While the Hawthorne Works was a large facility, estimates suggest the number of employees during the main experimental period was significantly less than 59,000. Figures often cited range around 12,000 to 13,000 employees during its peak operational years relevant to the studies.
Identifying Incorrect Statements
Based on the analysis above, statements (ii) and (iv) are the ones that are not true about the Hawthorne experiments.
Conclusion
Therefore, the combination of statements that are not true is ii & iv.
