This statement is true. The test statistic used to test hypotheses about the population variance is indeed given by F1F1F1S1F1F1F10², which follows a chi-squared distribution with n F1F1F1S1F1F1F10 1 degrees of freedom when the population is normally distributed with variance equal to F1F1F1S1F1F1F10².
