An industrial psychologist conducted an experiment in which 40 employees that were identified as “chronically tardy” by their managers were divided into two groups of size 20. Group 1 participated in the new “It’s Great to be Awake!” program, while Group 2 had their pay docked. The following data represent the number of minutes that employees in Group 1 were late for work after participating in the program. 114, 122, 137, 141, 137, 153, 138, 173, 128, 131, 143, 119, 128, 143, 148, 149, 149, 150, 121, 143 Determine whether the sample data could have come from a population that is normally distributed. Explain how you know.
