The percentage of physicians who are women is 27.9%. In a survey of physicians employed by a large university health system, 43 of 124 randomly selected physicians were women. Is there sufficient evidence at the 0.1 level of significance to conclude that the proportion of women physicians at the university health system exceed s 27.9% ? State the null hypothesis and alternative hypothesis, then find the test statistic, cr. value (or p-value) and make a decision.
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.
