Albert, a student of statistics, considered a random sample of the duration of 100 phone calls. He constructed the confidence interval with 95% confidence. Veronica selected her own random sample of 100 phone calls and constructed a confidence interval with 95% confidence. Is it possible that the confidence interval she obtained is different from the one Albert obtained? Explain why or why not. Suppose that they do not have information about the standard deviation of the population
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
