Mathematically, the T test takes a sample from each of the two sets and establishes the problem statement by assuming a null hypothesis that the two means are equal. The equal variance T test is used when the number of samples in each groups is the same, or the variance of the two data sets is similar.

Thus, the null hypothesis is true if the observed data in the sample do not differ from what would be expected on the basis of chance alone. T test can help determine which class fared better. The significance level is the probability that the test statistic will fall within the critical region when the null hypothesis is assumed.
