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.

Interpret the results found in the previous parts. Do the confidence intervals suggest a difference in the variation among waiting times? Does the
single-line system or the multiple-line system seem to be a better arrangement?
O A. The variation appears to be significantly lower with a single line system. The multiple-line system appears to be better.
B. The variation appears to be significantly lower with a multiple-line system. The single-line system appears to be better.
C. The variation appears to be significantly lower with a multiple-line system. The multiple-line system appears to be better.

In the provided table, the education information and incomes of 73,736 people are given. The rows are labeled with education status and the columns are labeled with income range. The total of all entries in each row gives the total number of people with the corresponding education status and similarly, the total of all entries of a particular column gives the number of people with the corresponding income range. Please answer subpart 4 and 5.
The Census Bureau Web site gives several choices for "average income" in its historical income data. In 2006, the median income of American households was $48,201. The mean household income was $66,570. The median income of families was $58,407, and the mean family income was $77,315. The Census Bureau says, “Households consist of all people who occupy a housing unit. The term ‘family’ refers to a group of two or more people related by birth, marriage, or adoption who reside together.” Identify the reason for mean incomes for households being higher than median incomes for households.
A company has 30 employees, including a director. The lowest salary among the 30 employees is $22,000. The director’s salary is $180,000, which is more than twice as much as anyone else’s salary. Decide for each of the following statements about the 30 salaries whether it is true, false, or you cannot tell on the basis of the information at hand. • The median salary is below $60,000.• The average salary is below $60,000.• If all salaries are increased by $1,000, that adds $1,000 to the average.• If the director’s salary is doubled, and all other salaries remain the same, that increases the average salary.• If the director’s salary is doubled, and all other salaries remain the same, that increases the median salary.• The standard deviation of the salaries is larger than $180,000

It is harder to get into graduate programs in psychology or history? We randomly selected five institutions from among all U.S. institutions with graduate programs. The first number for each is the minimum GPA for applicants to the psychology doctoral program, and the second is for applicants to the history doctoral program. These GPAs were posted on the website of the well-known college guide company Peterson's. Wayne State University: 3.0, 2.75 University of Iowa: 3.0, 3.0 University of Nevada-Reno: 3.0, 2.75 George Washington University: 3.0, 3.0 University of Wyoming: 3.0, 3.0 1. The participants are not people, explain why it is appropriate to use a paired-samples t test for this situation.
