RESEARCH METHODOLOGY

Detailed explanation-1: -The alternative/research hypothesis is always the opposite of the null hypothesis. For example, if a null hypothesis is expressed as H0:=1 H 0 : = 1, the alternative hypothesis is represented as H1:≠1 H 1 : ≠ 1 . Thus the given statement is True.

Detailed explanation-2: -Both Null and Alternative hypotheses are like True and False. If one hypothesis is supporting a particular situation then the other hypothesis is exactly opposite to that particular situation. So it is impossible for both hypotheses to be true or both hypotheses to be false.

Detailed explanation-3: -The alternative hypothesis states that a population parameter does not equal a specified value. Typically, this value is the null hypothesis value associated with no effect, such as zero. If your sample contains sufficient evidence, you can reject the null hypothesis and favor the alternative hypothesis.

Detailed explanation-4: -Statement of zero or no change. If the original claim includes equality (<=, =, or >=), it is the null hypothesis. If the original claim does not include equality (<, not equal, >) then the null hypothesis is the complement of the original claim. The null hypothesis always includes the equal sign.
