The table below shows the amount spent on advertising, in millions of dollars, over several months along with the corresponding sales, also in millions of dollars.

For a two-tail test with α = 0.05 and 5 - 2 = 3 degrees of freedom, tα/2 = 3.182. Because  = 3.50 is greater than  = 3.182, we reject the null hypothesis. Based on our sample, we conclude that the population correlation coefficient between advertising and sales is different than zero and is statistically significant.
