A recent study claims that the average age of murder victims in a small city was less than 24.5 years. A sample of 25 recent victims had a mean of 21.6 years and a standard deviation of 2.5 years. At a = 0.05, is the average age of the murder victims really what the study claims? Find the confidence interval. Round to the nearest tenths.

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.
