A sample of 3000 observations has a mean of 80 and a standard deviation of 10. The distribution is bell-shaped. Using the empirical rule, find what percentage of the observations fall in the intervals x+ 1s, x + 2s, and + 3s. Enter the exact answers. Approximately % of the observations fall in the interval x+ 1s. Approximately % of the observations fall in the interval x+ 2s.

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.
