Expert Solution
Step 1: Introduction
Null Hypothesis: A hypothesis which is tested for plausible rejection is called the Null Hypothesis (typically denoted by H0).
Alternative Hypothesis: Any hypothesis contradicting null hypothesis is called Alternative Hypothesis (typically denoted by H1).
Confidence interval: Confidence interval is an interval such that the probability of the unknown parameter to be included in the interval is equal to a preassigned probability, termed as confidence coefficient. In simple language, a (1 - α)% confidence interval has the probability to include the unknown parameter with probability (1 - α).
