She was so impressed, and she wants you to create another report for her. Her intention is to decrease the processing time per document.<\/span><br \/><\/span><\/div>\n<div><span style=\"font-size: 14px; cursor: auto; color: inherit;\"><span style=\"cursor: auto; color: inherit;\"><br \/><\/span><\/span><\/div>\n<div><span style=\"font-size: 14px; cursor: auto; color: inherit;\"><span style=\"cursor: auto; color: inherit;\"><span style=\"cursor: auto; color: inherit;\">Based on last week&#8217;s report, the average number of processed documents per hour was 15.11, with a standard deviation of 2.666. That is, one document was reviewed in 238.25 seconds. To be objective as much as possible, the manager spoke with an employee whose average was exactly 15 documents per hour. The employee claimed that if she was given a larger monitor, the processing time would be shorter.<\/span><br \/><\/span><\/span><\/div>\n<div><span style=\"font-size: 14px; cursor: auto; color: inherit;\"><span style=\"cursor: auto; color: inherit;\"><span style=\"cursor: auto; color: inherit;\"><br \/><\/span><\/span><\/span><\/div>\n<div><span style=\"font-size: 14px; cursor: auto; color: inherit;\"><span style=\"cursor: auto; color: inherit;\"><span style=\"cursor: auto; color: inherit;\"><span style=\"cursor: auto; color: inherit;\">They conducted an experiment with a large monitor and measured processing time. After reviewing 20 documents, the calculated average processing time per document was 190.58 seconds. The manager believes that a bigger monitor helped reduce the processing time for reviewing foreclosure documents.
