Again, you play the game where Bianca rolls a die and wins if it shows a 1 or a 2, otherwise you win. Out of 7 games, how many times does she have to win at least so that you would reject the null hypothesis (that the die is fair, results random) at the 5%-significance level? You can look up numbers in the Binomial table, but remember that one number is not enough. You can also use the Online Calculator, but then you need to convert the answer to percent.
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.
