Use the Principle of Inclusion and Exclusion to solve the following problem. Show your work and define the appropriate sets. Customers at a restaurant all tried the same meal: an egg sandwich, a side of hash browns, and a short stack of pancakes. After they had eaten, customers were asked whether or not they liked each of the parts of the meal. 73 said that they liked the egg sandwich, 28 said that they liked the hash browns, and 47 said that they liked the pancakes. 26 liked both the egg sandwich and hash browns, 21 liked the hash browns and pancakes, and 6 liked the sandwich and pancakes. If 98 customers liked at least one of the parts of the meal, how many of them liked all three parts of the meal?
Correlation
Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
Linear Correlation
A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.
Regression Analysis
Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.
