rom the 2010 Census, we learn that 14.6% of the residents of Oregon speak a language other than English at home. If we take random samples in size (n=100) and calculate the proportion of the sample that speaks a language other than English at home. a)Find the standard error associated with the sample proportion p(hat) b) Check if necessary conditions for assuming a normal model for p(hat) are met c) Write an appropriate model for sampling distribution for sample proportion p(ha
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.
From the 2010 Census, we learn that 14.6% of the residents of Oregon speak a language other than English at home. If we take random samples in size (n=100) and calculate the proportion of the sample that speaks a language other than English at home.
