Notice that PROC CORR automatically computes some simple statistics for each variable. The
output shows that the correlation between taste score and acetic acid is r=.54954. When
testing the null hypothesis that the population correlation between these two variables is zero
against the alternative hypothesis that it is different from zero, a low p-value of .0017 is
obtained, based on the sample size of N=30 cheeses. Thus, taste and acetic acid have a
significant positive relationship.
