Data collected in the 2010 U.S. census showed that men represent 49.2% of the population and women represent 50.8% of the population. A researcher plans to survey 5 rural hospitals and calculate the difference in sample proportions between male births and female births. At each hospital, the researcher will record the percentage of male births and the percentage of female births. Assume each hospital has about 100 births per year. We define the difference in sample proportions as “male” minus “female.” The standard error is about 0.07. Which sequence of sample differences is the most likely? 0.12, 0, -0.25, -0.08, 0.23 0.017, 0.039, -0.010, -0.081, -0.005 -0.016, -0.016, 0, -0.016, -0.016
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.
