Detailed explanation-1: -A sports publication states that 32% of married men cannot watch football games because their wives prevent it. You think that this is untrue. What is your null hypothesis? The proportion of married men who cannot watch football because their wives prevent it is 0.32.
Detailed explanation-2: -If there is an affirmation to support the alternative hypothesis, then the null hypothesis is maybe “rejected as false”. But, if the alternative hypothesis is not true, then there is no evidence the null hypothesis is true, hence it means the data “fails to reject” the null hypothesis.
Detailed explanation-3: -In layman’s terms, hypothesis testing is used to establish whether a research hypothesis extends beyond those individuals examined in a single study. Another example could be taking a sample of 200 breast cancer sufferers in order to test a new drug that is designed to eradicate this type of cancer.
