The sample data below show continine levels measured in a group of nonsmokers exposed to tobacco smoke and a group of nonsmokers not exposed to tobacco smoke. Use a O.05 significance level to test the claim that nonsmokers exposed to tobacco smoke have a higher mean continine level than nongmokers not exposed to tobacco smoke. Nongmokers exposed to Nongmokers not exposed to tobacco smoke tobacco smoke x = 60.6 x = 16.4 S = 138 62.5 n = 40 E 40 State the null and alternative hypotheses. Determine the test statistic, critical value, and conclusion about the claim.

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.
