Check Your Understanding Here, once again, is the stemplot of travel times to work for 20 randomly selected New Yorkers. Earlier, we found that the median was 22.5 minutes. 005555 1 0005 00 005 ICA3 Key: 45 is a New York worker FIRES 4 who reported a 45-minute travel 005 time to work. 1. Based only on the stemplot, would you expect the mean travel time to be less than, about the same as, or larger than the median? Why? 2. Use your calculator to find the mean travel time. Was your answer to Question I correct? 3. Would the mean or the median be a more appropriate summary of the center of this distribution of drive times? Justify your answer.

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.
