Astore 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?

Ok so the answer should be  D. The manager should check both relative frequencies by row and by column to look for an association.

Really hope this helps

God Bless you on your test!!!( ͡° ͜ʖ ͡°)

Step-by-step explanation:

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.

Hope this helps! :)

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
