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 1.5, Problem 74PE

The graph in Exercise 64 shows the number of student y enrolled in public colleges for selected years x, where x is the number of years since 1990. The table gives a partial list of data from the graph.

Chapter 1.5, Problem 74PE, The graph in Exercise 64 shows the number of student y enrolled in public colleges for selected

a. Use the data in the table to find the least-squares regression line. Round the slope to 2 decimal places and the y-intercept to 1 decimal place.

b. Use a graphing utility to graph the regression line and the observed data.

c. Assuming that the linear trend continues use the model from part (a) to predict the number of students enrolled in public colleges for the year 2020.

d. By how much do the results of part (c) differ from the result of Exercise 64(d)?
