Given below are two statements : One is labeled as Assertion A and the other is labeled as Reason R. Assertion (A) : When Null Hypothesis (H0) is rejected, researcher's hypothesis (H1) is accepted.  Reason (R) : Null Hypothesis (H0) is a chance hypothesis and as such (H1) being true, the researcher's hypothesis lies in the domain of acceptability.  In the light of the above statements, Choose the most appropriate answer from the options given below :

Bayes Theorem is given by where
1. P(H) is the probability of hypothesis H being true.
2. P(E) is the probability of the evidence(regardless of the hypothesis).
3. P(E|H) is the probability of the evidence given that hypothesis is true.
4. P(H|E) is the probability of the hypothesis given that the evidence is there.
Given below are two statements Statement I: In research, 'Null hypothesis' when rejected, offers the scope for accepting the alternative or substantive research hypothesis. Statement II: When the Null hypothesis is rejected, there will be chances for committing 'Beta' rather than 'Alpha' error.

The following sentences form a paragraph. These four parts are numbered as P, Q, R and S. They are not given in their proper order. Read the sentences and choose the alternative that arranges them in correct order. P. The hypothesis was proposed as an explanation for the increased prevalence of type-2 diabetes in certain populations by American geneticist James V. Neel. Q. Thrifty genes refers to a scientific hypothesis which states that obesity in some human beings can be explained by the existence of a ‘thrifty gene’ that aided the storage of excess energy as fat. R. The same genes, however, turned into a biological liability that led to obesity in some people. S. According to the hypothesis, certain genes, by helping in the storage of energy as fat, might have enabled human ancestors live through periods of famine, thus enhancing their chances of survival.
