Question 9

The manager of the New England Patriots conducted a large survey.He wanted to know if there was an association between fans being "season ticket holders" vs."non-season ticket holders" and whether they "bought" vs."didn't buy" team merchandise at the game.Because his survey included these measurements,he used SPSS to run a Pearson correlation coefficient that turned out to be 0.88 with a Sig.value of .001.This meant there is a significant relationship.
