Question
How to perform a two-sample test for the equality of the normal mean for independent samples with known(equal or unequal) variances? So for one-sample test,
How to perform a two-sample test for the equality of the normal mean for independent samples with known(equal or unequal) variances?
So for one-sample test, we have t-test for unknown variance and z-test for known variance. Does the same also apply to two-sample test? If so, what is the critical value of the z-test?
