How to define ho and HA?
H0 is called the null hypothesis and HA is called the alternative hypothesis. The union of null and alternative hypothesis defines a hypothesis H ∈ Θ=Θ0 ∪ ΘA called the maintained hypothesis. A hypothesis is called simple if it completely specify the probability distribution and otherwise com- posite. The null hypothesis, H0, is a statistical proposition stating that there is no significant difference between a hypothesized value of a population parameter and its value estimated from a sample drawn from that population.The null hypothesis (often denoted H0) is the claim in scientific research that the effect being studied does not exist.
What does HO stand for in statistics?
Formally, a statistical hypothesis testing problem includes two hypotheses. These hypotheses are referred to as the null hypothesis (H0), and the alternative hypothesis (HA). The null hypothesis, denoted by H0, is a statement about a population parameter. The alternative hypothesis is denoted by H1. The null hypothesis will be rejected if it appears to be inconsistent with the sample data and will not be rejected otherwise.
