na previous year, 58% of females aged 15 and older lived alone. A sociologist tests whether this percentage is different today by conducting a random 350 females aged 15 and older and finds that 210 are living alone. Is there sufficient evidence at the a 0.01 level of significance to conclude the propo changed? Because npo (1-Po) = 85.3 >10, the sample size is less than 5% of the population size, and the sample is given to be random, he requirements for testing the hypothesis Round to one decimal place as needed.) are satisfied. dentify the null and alternative hypotheses for this test. versus H1: Type integers or decimals.

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.
