WebA moment’s thought should convince one that it is 2.5%. This is known as a one sided P value , because it is the probability of getting the observed result or one bigger than it. However, the 95% confidence interval is two sided, because it excludes not only the 2.5% above the upper limit but also the 2.5% below the lower limit. WebIn example 2, if p is less than 0.40, you would still not want to build the cafeteria. After all, it could be the case that 30% or 10% or even 0% of the people are interested in the meal plan. If you were to set H_0: p = 0.40, then you would ignore all these less than options, so we need the less than or equal sign. Comment.
