Suppose the average commute time of your employees is unknown. The standard deviation of their commute time is estimated as 25.6 minutes.

How many employees must be included in a sample to have a 90 percent confidence interval for the average commute time with a confidence interval width of no more than 11 minutes?

Note that the correct answer will be evaluated based on the z-values in the summary table in the Teaching Materials section.

Note that the correct answer will be evaluated based on the full-precision result you would obtain using Excel.

Suppose you are working for a regional residential natural gas utility. For a sample of 100 customer visits, the staff time per reported gas leak has a mean of 206 minutes and standard deviation 40 minutes. The VP of network maintenance hypothesizes that the average staff time devoted to reported gas leaks is 212 minutes.

At a 5 percent level of significance, what is the lower bound of the interval for determining whether to accept or reject the VP’s hypothesis?
