Complete the relative frequency distribution below. Relative Cause Frequency Pilot error 46.4 % Other human error 9.1 % Weather 12.3 % Mechanical problems 13.9 % Sabotage 18.3 % (Round to one decimal place as needed.) What is the most serious threat to aviation safety, and can anything be done about it? A. Weather is the most serious threat to aviation safety. Weather monitoring systems could be improved. B. Mechanical problems are the most serious threat to aviation safety. New planes could be better engineered. C. Sabotage is the most serious threat to aviation safety. Airport security could be increased. D. Pilot error is the most serious threat to aviation safety. Pilots could be better trained.
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.
same question but diffrent prablem.
Relative frequency= Frequency of the class*100/total frequency %
