Detailed explanation-1: -A null hypothesis is a type of conjecture in statistics that proposes that there is no difference between certain characteristics of a population or data-generating process. The alternative hypothesis proposes that there is a difference.

Detailed explanation-2: -The hypothesis that can be called the hypothesis of no difference is the null hypothesis. The null hypothesis will always state that the values of the point estimates taken from the population will be equal (i.e., there will be no difference, statistically speaking, between the values).

Detailed explanation-3: -In scientific research, the null hypothesis (often denoted H0) is the claim that no relationship exists between two sets of data or variables being analyzed.

Detailed explanation-4: -A scientific hypothesis is a statement of what theresearcher expects to find upon conducting a study. A statistical hypothesis, however, is a statement of what the statisticianexpects NOT to find. For this reason it is called a NULL hypothesis.

Detailed explanation-5: -Revised on 6 December 2022. The null and alternative hypotheses are two competing claims that researchers weigh evidence for and against using a statistical test: Null hypothesis (H0): There’s no effect in the population. Alternative hypothesis (HA): There’s an effect in the population.
