According to a manager it takes an average weekday commute of 39 minutes with a Standard Deviation of 7 minutes for the employees to get to work when they use their personal vehicles for their office commute while management set a policy of not more than 40 minutes for their daily one-way commute. A survey conducted one day on 70 employees showed an average of 34 minutes commuting time using the metro public transportation system with a Standard Deviation of 21 minutes. For the employees choosing to increase their chances to come on time using personal transportation their variation should be reduced to ___________?

• 1 minute
• 6 minutes
• 3.5 minutes
• Eliminate it to 0.0 minutes

Which statement(s) are true about the Fitted Line Plot shown here? (Note: There are 2 correct answers).
