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.

Transcribed Image Text:A real estate agency says that the mean home sales price in City A is the same as in City B. The mean home sales price for 30 homes in City A is $127,474. Assume the population standard deviation is $25,876. The mean home sales price for 30 homes in City B is $112,258. Assume the population standard deviation is $27,113. At a = 0.01, is there enough evidence to reject the agency's claim? Complete parts (a) through
(d) below.
(a) Identify the claim and state H, and Ha.
What is the claim?
O A. The mean home sales price in City A is the same as in City B.
O B. The mean home sales price in City A is greater than as in City B.
O C. The mean home sales price in City A is less than in City B.
O D. The mean home sales price in City A is not the same as in City B.
Let City A be sample 1 and let City B be sample 2. Identify Ho and Ha.
Họ: H1
Ha: H1
