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 p…

Chapter 1.3, Problem 93E

Net Income The net income of Amazon decreased from $0.63 billion in 2011 to –$0.24 billion in 2014.49

a. Use this information to find a linear model for Amazon’s net income N (in billions of dollars) as a function of time t in years since 2010.

b. Give the units of measurement and interpretation of the slope.

c. Use the model from pan (a) to estimate the 2013 net income. (The actual 2013 net income was approximately $0.27 billion.)
