1. For each customer state, output the state abbreviation (CustState) and the average household income for all customers in that state. Order results alphabetically by state abbreviation and be sure that the average household income column includes a meaningful column name. (Hint: You only need to use one table for this query since you are not asked to give the actual name of the state.) (Remember: only copy the top 10 rows – do not worry about the Headers or Copy with Headers).

2. Output the customer name (Fname and Lname), marital status, state (use the actual state name), and household income for all customers located in Colorado (CO), Utah (UT), Washington (WA), and Wyoming (WY) who have a household income of under $119,500 and are married. Order results alphabetically by last name. Your query should not include the OR operator. (Remember: only copy the top 10 rows – do not worry about the Headers or Copy with Headers).

4. For each state, what percentage of the state’s population purchased a DustBunny vacuum (assume everyone in the customer table has purchased a DustBunny vacuum)? Your output should include the state name, population, number of purchasers from that state, and the percentage (show as a decimal). Order the output from the highest percentage to the lowest and make sure each column has a usefully descriptive name. (Remember: only copy the top 10 rows – do not worry about the Headers or Copy with Headers).

5. Show the five orders that included the highest number of items (e.g., if an order included 2 of one type of vacuum and 1 of another, that equates to three items). For each order, show the customer first name, customer last name, number of items, the order date, and the total value of the order. Order results from highest number of items to lowest.

1. Assume you wanted to add another state to the database, the state of Nevernia. Nevernia has a state code of NA, is in region 2, and has a population of 40,000. Nevernia is a small state. Include in your submission (1) the query that you would use to add this additional record to the database and (2) the output of a query that shows the StateIDS, RegionID, Population, and StateName of all states with a population under 1,000,000 AS WELL AS the query you used to generate this output.

2. Vivian Dunn (CustID 936) was recently married. Vivian has formally requested a name change and also a marital status change. Change the Customer table in your personal database so that Vivian Dunn’s last name is now Bryant and her marital status is changed from ‘single’ to ‘married.’ Run the following query to verify Vivian’s Customer ID and to get acquainted with all the customers in the Customer table with the Lname “Dunn” or “Bryant” (note: only one last name—Vivian’s—of the 6 records should change when you run your UPDATE query):

SELECT *

FROM Customer

WHERE Lname = 'Dunn' OR Lname = 'Bryant';

Include in your submission (1) the query that you would use to change (update) Vivian’s record in the database and (2) the output of a query that shows Vivian’s updated record AS WELL AS the query you used to generate this output.
