The 2008 Workplace Productivity Survey, commissioned by LexisNexis and prepared by WorldOne Research, included the question, "During the average workday, how many hours do you spend conducting online research?" Let x = the number of hours a legal professional spends on online research during a typical workday. Suppose that x is normally distributed with a known standard deviation of 5.A sample of 250 legal professionals was surveyed, and the sample's mean response was 2.7 hours. Use the sample information to estimate , the mean number of hours a legal professional spends on online research during a typical workday.

The sampling distribution of XXis normal with a mean of 0.316228 and a standard deviation of 5 .

Use the following Distributions tool to develop a 95% confidence interval estimate of the mean number of hours a legal professional spends on online research during a typical workday.
