Suppose that the age of students at George Washington Elementary school is uniformly distributed between 6 and 10 years old. 47 randomly selected children from the school are asked their age. Round all answers to 4 decimal places where possible. What is the probability that the average of 47 children will be between 8 and 8.5 years old?
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.
