Last week my manager asked me to analyze staffing needs for the Foreclosure Department. She was so impressed $,$ that she wanted me to create another report for her. Her intention is to decrease the processing time per document. Based on last week$$s reports $,$ the average number of processed documents per hour was $15\mathrm{.}11,$ with a standard deviation of $2\mathrm{.}666.$ One of the documents was reviewed in $238\mathrm{.}25$ seconds. 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. They conducted an experiment with a large monitor and measured processing time. After reviewing $20$ documents $,$ the calculated average processing time per document was $190\mathrm{.}58$ seconds. The manager believes that a bigger monitor helped reduced the processing time for reviewing foreclosure documents $.$ I will conduct a hypothesis test using a $95\%$ confidence level $,$ which means that the significance level is a $0\mathrm{.}05.$
