Explanation:
Detailed explanation-1: -Revised on December 6, 2022. The null and alternative hypotheses are two competing claims that researchers weigh evidence for and against using a statistical test: Null hypothesis (H0): There’s no effect in the population. Alternative hypothesis (Ha or H1): There’s an effect in the population.
Detailed explanation-2: -To graph a significance level of 0.05, we need to shade the 5% of the distribution that is furthest away from the null hypothesis. In the graph above, the two shaded areas are equidistant from the null hypothesis value and each area has a probability of 0.025, for a total of 0.05.
