State the requirements to perform a goodness-of-fit test. Choose the correct answer below. Select all that apply. A. at least 90% of expected frequencies greater than or equals10 B. at least 80% of expected frequencies greater than or equals10 C. all expected frequenciesgreater than or equals5 D. at least 80% of expected frequencies greater than or equals5 E. at least 90% of expected frequencies greater than or equals5 F. all expected frequenciesgreater than or equals1

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.

The main requirement to perform a goodness-of-fit test in the given scenario is that the all expected frequencies is greater than or equals 5. Option C is correct.

Goodness of fit test:

It is a statistical hypothesis test mainly used to test how well a sample data fits a distribution from a certain population.

The expected value of each variable needs to be at least five in order to use this test, Not less than 5, but value can be greater than 5.

Other requirements are,

The sampling method must be random sampling.

The variable under study must be categorical.

Therefore, the main requirement to perform a goodness-of-fit test in the given scenario is that the all expected frequencies is greater than or equals 5.
