a) What is the probability that at least 3 have conditions caused by outside factors? b) What is the probability of 5 of the patients have conditions caused by natural occurrences? c) What is the expected number that has conditions caused by natural occurrences?
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.
Heart failure is due to natural occurrences in 95% of cases or outside factors in 5% of cases. Suppose 15 patients are hospitalized with heart failure.
a) What is the
b) What is the probability of 5 of the patients have conditions caused by natural occurrences?
c) What is the expected number that has conditions caused by natural occurrences?
d) Out of 100 patients hospitalized with heart failure, what is the approximate probability that less than three have conditions caused by outside factors?
