Final answer:
A feasibility study is typically conducted by businesses or organizations, and in this case, a major food manufacturer investigates the decline in skinny french fries' sales through a test of independence across different regions.
Step-by-step explanation:
The entities majorly requiring a feasibility study are often businesses or organizations embarking on new projects, investments, or product launches.
In the scenario provided, a major food manufacturer is questioning why sales for its skinny french fries have been on the decline.
To investigate the matter, the company carries out a feasibility study, particularly conducting a test of independence to see whether the type of fries sold is independent of the geographical area. This involves statistical analysis, commonly using a Chi-square test, to determine if there is any association between two categorical variables: the type of fries and the regions of the country.
