The following frequency table contains data on home sale prices in the city of Summerhill for the Month of June. For a randomly selected sale price between $80,000 and $265,900, let X denote the number of homes that sold for that price. Find the probability distribution of X. Sale Price (in thousands $) Frequency (homes sold) P(X = x) 80.0 – 110.9 3 111.0 – 141.9 6 142.0 – 172.9 5 173.0 – 203.9 12 204.0 – 234.9 3 235.0 – 265.9 1
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.
