After studying and reviewing the concepts and practices of correlation and simple linear regression, solve the following exercise using Excel:
1. The following sample observations were randomly selected:
X: 5 3 6 3 4 4 6 8
Y: 13 15 7 12 13 11 9 5
2. Consider the following aspects when submitting your test:
•
o Graph the scatter plot or dispersion
o Determine the correlation coefficient.
o Determine the regression equation.
o Find the value of the dependent variable when X = 7.
o Is the regression model adequate? Justify your answer. Which test determines this?
3. Present your answers with the aspects learned so far about correlation and simple linear regression.
