) The personnel manager of a consumer products company asked a random sample of 300 employees how they felt about how they felt about going to a flex schedule, which would allow employees to choose their arrival and leaving times, on a five day schedule. This would replace the current schedule which allows employees to choose between a four day, ten hour schedule and a five day, eight hour schedule. The following table gives a breakdown of their preferences by gender.
