A hospital director is told that 68% of the emergency room visitors are insured. Thedirector wants to test the claim that the percentage of insured patients is over theexpected percentage. A sample of 100 patients found that 75 were insured. At the0.05 level, is there enough evidence to support the director's claim?a) Find the value of the test statistic. Round your answer to two decimal places.b) Determine the ����-value of the test statistic. Round your answer to four decimalplaces.c) State the conclusion of the hypothesis test.
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.
