Suppose the average commute time of your employees is unknown. The standard deviation of their commute time is estimated as 30.8 minutes.How many employees must be included in a sample to create 90 percent confidence interval for the average commute time with a confidence interval width of no more than 14 minutes?Note that the correct answer will be evaluated based on the z-values in the summary table in the Teaching Materials section.Remember to round your answerupto an integer.Note that the correct answer will be evaluated based on the full-precision result you would obtain using Excel.
