Informatics and Nursing Textbook Update

When working on the eBook I am writing about data analysis, I noticed another error in the 4th edition of the Informatics and Nursing textbook.  On page 141, 2nd paragraph the symbol for equals sign is incorrect.  It should appear as (=).  While many might recognize the error, new learners might find the symbol confusing.  On page 148, the names of the pie charts should have been changed to % instead of #.  The data in the spreadsheet were numbers, but pie charts are used to display percentages.  Therefore the column header # Falls should be been % Falls when that column is used for a pie chart.
