WebThe null and alternative hypotheses are two mutually exclusive statements about a population. A hypothesis test uses sample data to determine whether to reject the null hypothesis. The null hypothesis states that a population parameter (such as the mean, the standard deviation, and so on) is equal to a hypothesized value.
WebSo far, understanding the concept of null hypothesis, let’s now discuss the null hypothesis formula: Here, the null hypothesis formula is given below. H0: p = p0. The formula for the alternative hypothesis can be written as: Ha = p >p0, and < p0≠ p0. The formula for the test static is denoted by: Z = P − P 0 P − P 0 n.
