How to do a two tail hypothesis test?
This is a Two tail test, so the probability lies on both side of the distribution. So 0.025 each side and we will look at this value on the z table. Since the level of significance is 0.025 each side, we need to find 0.025 in the z table. Once we find that value from the table, we need to extract z value.
What are the types of errors in hypothesis testing?
There is 2 type of errors which can arise in hypothesis testing: type I and type II. Type 1: When the null hypothesis is true but it is rejected in the model. The probability of this is given by the level of significance. So if the level of significance is 0.05, there is a 5% chance that you will reject the null which is true.
When to use Type 1 or Type 2 hypothesis testing?
Type 1: When the null hypothesis is true but it is rejected in the model. The probability of this is given by the level of significance. So if the level of significance is 0.05, there is a 5% chance that you will reject the null which is true. Type 2: When the null hypothesis is not true but it is not rejected in the model.

Once more, the formula for the test is based on the z statistic, simply it takes connected a different grade since it involves two samples: the null hypothesis for this test is that both sample distribution proportions come from the same universe proportion.
My experience has been that at one time students understand the logic of guess testing, the entry of new models is a peanut change in the procedure.
