Suppose that half of all students (50%) in campus dormitories are dissatisfied with the food service. A random sample of 64 students was taken. What is the probability that the number of students in the sample who were dissatisfied with the food service was between 30 and 34 (inclusive)? (Use the normal approximation to the binomial distribution, without the continuity correction.).
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.
