About 22% of the residents of Ohio were born outside the United states. You choose an SRS of 1000 Ohio residents for a sample survey on immigration issues. You want to find the probability that 250 or more of the people in your sample were born outside the United states. a) You would like to use normal approximation for the sampling distribution of a sample proportion to answer this question. Explain why you can use approximation b) What is the probability that more 250 or more of the people in your sample were born outside the United states.
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.
