This statement is a direct application of the Principle of the Chi-Square Test, which states that the sum of the expected cell frequencies equals the sum of the observed cell frequencies under the null hypothesis. Since the null hypothesis in this case is that there is no difference in laptop ownership between males and females, it follows that the sum of the expected cell frequencies is equal to the sum of the observed cell frequencies.
