# Correlation and Regression (Descriptive Statistics)

1. Testing for a linear Correlation:

Use the scatterplot and the linear correlation coefficient r to determine whether there is a correlation between the two variables.

x 1 2 2 5 6

y 2 5 4 15 15

2. Finding the Equation of the Regression Line:

Use the given data to find the equation of the regression line.

x 1 2 2 5 6

y 2 5 4 15 15

Please show step by step process with explination and include the scatterplot. Please show all on a word doc. Do not use word doc verion 2007. Thank you.
