A store manager wishes to investigate whether there is a relationship between the type of promotion offered and the number of customers who spend more than $30 on a purchase. Data will be gathered and placed into the two-way table below. Customer Spending by Promotion Run Customers Spending More than $30 Customers Spending $30 or Less $10 off $50 15% off $5 off $25 Buy-1-Get-1 Half Off Which statement best describes how the manager can check if there is an association between the two variables?
The answer is D. The manager should check both relative frequencies by row and by column to look for an association.
This is because the manager wants to know whether a customer buys more than $30 worth of stuff at their store with coupons taking off a lot or a little bit of the price.
