Arbitron Media Research Inc. conducted a study of the iPod listening habits of me 5. and women. One facet of the study involved the mean listening time. It was discov ered that the mean listening time for a sample of 10 men was 35 minutes per day The standard deviation was 10 minutes per day. The mean listening time for a sam. ple of 12 women was also 35 minutes, but the standard deviation of the samnia was 12 minutes. At the .10 significance level, can we conclude that there is a diiar. ence in the variation in the listening times for men and women?

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.
