Question

How, in general, do you calculate the expected frequency for a cell in a goodness-of-fit test?

a)Use the total number of observations divided by the number of categories.

b)Multiply the specified proportion for that cell (found in H0) by the total sample size.

c)Multiply the total count in the table by the associated sample proportions for the row and column that define the cell (i.e., the row p-hats and column p-hats).

D)None of these approaches is correct.

e)The expected frequency is equal to the proportion specified in H0 for that cell.

Explanation / Answer

For a goodness of fit test, we calculated the expected frequnecy on the basis of:

Multiply the specified proportion for that cell (found in H0) by the total sample size.

Option b is correct.
