t-test for population mean
This is meant to see the significance of the difference between and assumed population mean and a sample mean.This is done with a population with an assumed mean and an unknown variance ,a random sample of size n is taken and a sample mean is circulated and also the standard deviation using the formula.The t -test can also be performed with little modification for two population means wherein the variance are unknown but equal and also variance are unknown and unequal.
x2 test for population variance
This test is basically to see the difference between the sample variance S2 and assumed population variance.
x2 test for goodness of fit
This test is meant to see the significance of the differences between the observed data arranged in k classes and theoretically expected frequencies in the same.
