Write some SAS code that that will answer the questions below using the SAS file above.

These questions get at your understanding of different levels of summarization and in more general terms, how you approach programming problems. There are many ‘right’ answers.

You do not have to use the original dataset as input to each question, you may want to summarize at one step and use that summarization in later steps.

1. Total and average amount spent by category
2. Which category has the highest average purchase
3. What is the average number of categories that customers purchase
4. What is the average and total amount by customer
5. What is the average number of days between purchases (as of today)
