Please Download "wages" from Canvas (the link to
this dataset is right below the HWA1 questions - it is
a Microsoft excel worksheet) and store it in your
favorite folder.
It contains 797 observations and 16 variables. The
"state" variable gives the names of the states
involved in this dataset.
• You need to have excel on your computer to open
this dataset.
i. You should use File > Import > Excel Spreadsheet
etc. as done in class 3 convert this file into a
Stata dataset. Once you are done, write the final
STATA code that makes the transformation of an
excel file to a STATA file possible.
ii. Write a code that will close the log file that has
been open since Question 1 part ii.

- West Virginia has one of the highest divorce rates in the nation, with an annual rate of approximately 5 divorces per 1000 people (Centers for Disease Control and Prevention website, January 12, 2012). The Marital Counseling Center, Inc. (MCC) thinks that the high divorce rate in the state may require them to hire additional staff.
