Answer: C. all expected frequencies is greater than or equals5

Explanation: The goodness of fit test is mainly used to test if sample data fits a distribution from a certain population.

The expected value for each cell needs to be at least five in order for you to use this test, Not less than 5, but greater than 5. Which is why option C is correct for performing a goodness-of-fit test.

Other requirements includes;

• The sampling method is a simple random sampling.

• The variable under study is categorical.
