In order to test if an observed frequency distribution with five classes is normally distributed, we need to find the expected, normally distributed class frequencies based on the mean and standard deviation of the distribution. This can be done using a normal probability density function. The other options (t-statistic, class marks, class relative frequencies) are not relevant for this specific test.
