) 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.
a) Is there sufficient evidence to conclude that the preference of either schedule is related to gender? (=.05)
b) If there is a relationship between gender and schedule preference, how would you describe it?
schedule
current flex
male 110 50
female 50 90

a) 160 males answered the survey; and 110/160 = 68.75% preferred the current schedule.

140 females answered the survey, and only 50/140 = 35.71% preferred the current schedule, and 90/140 preferred the flex schedule

b) One way of describing the preferences is that males are almost twice as likely as females to prefer the current schedule.
