Find the following and round your answers to four decimals. a) Find the probability of exactly 7 people arrive between 5 and 6pm. b) Find the probability that at most 4 people arrive in between these times. c) Find the probability that between 5 and 9 people arrive between 5 and 6pm
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.
