Commercial dredging operations in ancient rivers occasionally uncover archaeological artifacts of great importance. One such artifact is Bronze Age spearheads recovered from ancient rivers in Ireland. A recent study gave the following information regarding discoveries of ancient bronze spearheads in Irish rivers. A Pareto chart is a bar graph in which each bar height shows the frequency of an event. The bars are arranged from left to right according to decreasing height. In this case, the event is spearheads recovered from ancient rivers.   Begin by identifying the river with the highest frequency. Refer to the frequency table provided below. The highest frequency corresponds to the __________ (Bann, Blackwater, Erne, Shannon, Barrow) River, in which _________ (25, 7, 15, 29, 14) spearheads were found.

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.
