Answer 1

HYPOTHESIS:
​ Hypothesis is an assumption or concession made for the sake argument.
RESEARCH HYPOTHESIS:(H1)
​    A research hypothesi is the statement created by researchers when they speculate upon the outcome of a research or experiments. A clear statement that describes an expected relationship between variables.
EXAMPLE:
​    Employee's job satisfaction is positively related to their commitment to the organization.
NULL HYPOTHESIS:(H0)
​ It's equality or of unrelatedness. Accepted or rejected in favour of an alternative.Specifically the hypothesis that an observed difference is due to chance alone and not due to systematic cause.
EXAMPLE:
   In a clinical trial of a new drug,the null hypothesis is might be that the new drug is no better,on average,than the current-drug.There is no differnce between the two drugs on average.
​NULL AND RESEARCH HYPOTHESIS:
-- Directional and One-tailed tests
​ --Non directional and Two-tailed tests
   --Good hypothesis
​ --Clear,declarative,brief
   --Tell us about expected relationship between variables
      --Reflects theory,past research
   --Are testable.
