The data on the time (in minutes) taken using both a private transportation system and a public transportation system for a sample of ten employees for both modes of transportation are given below: 2+2+2=6 a. Considering the travel times (in minutes) of employees using private transport, compute the 2 -scores. b. Considering the travel times (in minutes) of employees using public transport, compute the z-scores. c. Based on z-scores, do the data for employees using private transport and public transport contain any outliers
