How to test hypothesis for difference in proportions?
The formula for the test of hypothesis for the difference in proportions is given below. Test Statistics for Testing H 0: p 1 = p . Where is the proportion of successes in sample 1, is the proportion of successes in sample 2, and is the proportion of successes in the pooled sample.
When to use null hypothesis for two sample proportions?
For a test for two proportions, we are interested in the difference between two groups. If the difference is zero, then they are not different (i.e., they are equal). Therefore, the null hypothesis will always be: H 0: p 1 − p 2 = 0. Another way to look at it is H 0: p 1 = p 2.

How is the hypothesis test based on probability?
Since the hypothesis test is based on probability, random selection or assignment is essential in data production. Additionally, we need to check whether the sample proportion can be np ≥ 10 and n (1 − p) ≥ 10. Step 3: Assess the evidence. Determine the test statistic which is the z -score for the sample proportion.
