What was the age distribution of nurses in Great Britain at the time of Florence Nightingale? Suppose we have the following information. Note: In 1851 there were 25,466 nurses in Great Britain. (a) Using the age midpoints x and the percent of nurses, do we have a valid probability distribution? Explain. A. Yes. The events are distinct and the probabilities sum to 1. B. Yes. The events are distinct and the probabilities do not sum to 1. C. No. The events are indistinct and the probabilities sum to 1. D. No. The events are indistinct and the probabilities do not sum to 1. (b) Choose a histogram that graph the probability distribution in part (a). (c) Find the probability that a British nurse selected at random in 1851 would be 60 years of age or older.
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.
