Explanation:
Hypothesis is a mathematical relationship statement, whose statistical significance is tested.
'Does the color blue make people feel calmer'
- Null Hypothesis [H0] : Blue color has no impact on people's calmness. C = C0 {C being the post case calmness, C0 usual average calmness}
- Alternate Hypothesis [H1] : Blue color has increasing impact on people's calmness. C > C0
Hypothesis Testing : The test can be done by t test & p test. If calculated t value > tabulated t value & p value < significance p value, we reject H0 & accept H1. In case of vice versa, we reject H1 & accept H0
