Explanation:
Detailed explanation-1: -The significance level (denoted by the Greek letter alpha-a) is generally set at 0.05. This means that there is a 5% chance that you will accept your alternative hypothesis when your null hypothesis is actually true.
Detailed explanation-2: -The researcher pre-specified an alpha of 0.05, implying they wanted the chance of the null hypothesis to be less than 5% before rejecting the null hypothesis.
Detailed explanation-3: -A P-Value < or = 0.05 is considered statistically significant. It denotes strong evidence against the null hypothesis, since there is below 5% probability of the null being correct. So, we reject the null hypothesis and accept the alternative hypothesis.
