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 attending meetings?" Let x = the number of hours a legal professional spends attending meetings during a typical workday. Suppose that x is normally distributed with a known standard deviation of 4.2. A sample of 250 legal professionals was surveyed, and the sample's mean response was 2 hours. Use the sample information to estimate u, the mean number of hours a legal professional spends attending meetings during a typical workday. The sampling distribution of x is normal with a mean of 2 and a standard deviation of 4.2 Use the following Distributions tool to develop a 90% confidence interval estimate of the mean number of hours a legal professional spends attending meetings during a typical workday.

Transcribed Image Text: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 attending meetings?" Let x = the number of hours a legal professional spends attending meetings
during a typical workday. Suppose that x is normally distributed with a known standard deviation of 4.2.
A sample of 250 legal professionals was surveyed, and the sample's mean response was 2 hours. Use the sample information to estimate u, the mean
number of hours a legal professional spends attending meetings during a typical workday.
The sampling distribution of x is normal with a mean
of 2
and a standard deviation
of 4.2
Use the following Distributions tool to develop a 90% confidence interval estimate of the mean number of hours a legal professional spends attending
meetings during a typical workday.
