Determine if the following statement is true or false.Why?

The expected frequencies in achi-square test for independence are found using the formula below.

Expectedfrequency=(rowtotal)(columntotal)/tabletotal

Choose the correct answer below.

A.

True. The area to the right of this value in the correspondingchi-square distribution gives theP-value for the test.

B.

False. The expected frequencies for achi-square test are given by OiEi / Ei, where i represents cell number.

C.

True. It is a simplification of multiplying the proportion of a row variable by the proportion of the column variable to find the proportion for acell, then multiplying by the table total.

D.

False. This formula gives the expected proportion. The(table total) factor in the denominator on the right should be squared.
