Use a 90% confidence level for your estimate and round your answers to four decimal places. Here is the sample data you collected ("used" indicates usage of the new feature, "not used" indicates no usage): used, not used, used, not used, used, used, not used, not used, used, used, not used, not used, used, not used, used, not used, not used, not used, used, used, not used, used, not used, used, not used, not used, used, used, not used, used HELPFUL NOTE: Copy and paste the data into an Excel workbook. If it jams it all into a single cell, use the "text to columns" function in the Data ribbon to tell it to split it into individual cells using a comma delimiter.
