Question:
Consumer spending. An analyst at a large credit card bank is looking at the relationship between customers’
charges to the bank’s card in two successive months.

After verifying all the data with the company’s CPA, he concludes that the model is a useful one for predicting one month’s charges from the other. Examine the data and comment on his conclusions.
