WebAug 1, 2024 · A hypothesis is a tentative explanation about an observation that can be tested. It's just a starting point for further investigation. Any one observation usually … Web∙ The "estimator" in this case is the difference between proportions. This is what we are trying to estimate from the question. Thus, Estimator = p̂₁﹣ p̂₂ ∙ The "null" in this case is zero. Because we are assuming both proportions are the same and equal, meaning there is no difference. Thus, Null = 0
