n a recent study it was found that of 450 physicians polled 162 were women and of 530 nurses polled 445 were women. Test the claim using the traditional method of hypothesis testing that the proportion of nurses who are women is greater than the proportion of physicians who are women. Assume a significance level of 0.01 Let p1=the proportion of nurses who are women Let p2=the proportion of physicians who are women e) What critical values are there? z= f) What is the value of the test statistic? z= g) What is the decision? h) What is the conclusion?
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.
