Properties of Z-test

Here we discuss some important properties of the Z-test:
Z-test gets the power analysis of the test if it is available.
It determines the Confidence Interval for the unknown parameter and also gets an estimated value for it.
It also takes into account the hypothesized value of the parameter in the test and determines the significance of the null or alternative hypothesis.
From Z-test we can also calculate the standard error of the estimated value.
Another important property or advantage of Z-test is that the distribution of the test statistic is always known and easy to deal with.
