I am a consultant from the Excellent Consulting Group. My client, the ABC Furniture Company, believes that the number of customers who visit the store during any particular month is related to the total sales for the month in question, i.e. the client believes that there is a relationship between higher customer traffic and higher total sales.

I was wondering if you could help me with this. "
