Question 1

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 while they use their personal vehicles for their office commute while the 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. If the Standard Deviation is uncontrollable then the other option to increase the probability of coming in on time via personal vehicles to work could be ____________?

AIncrease the average time of commute

BMaintain the average time of commute and change route to work

CReduce average commute time to work by departing earlier

DChange policy at work and request for flexible times based on location

Answer : C

Answer : A

Question 5

Due to excessive pollution, GREEN Solutions Inc. is considering subsidizing public transportation to work for its employees. According to the manager it takes an average weekday commute of 39 minutes with a Standard Deviation of 7 minutes for the employees to get to work while they use their personal vehicles for their office commute while the 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. Assuming a Normal Distribution for the commute times by either personal or public transportation, which of these is true?

AThe probability that they would arrive on time using personal vehicles is much higher than using the metro public transportation system (MPTS)

BThe probability that they would arrive on time using the MPTS is much higher than using their personal vehicles

CThe two probabilities are about the same excepting in one case the consistency is higher than the other

DWe need to compile more data around weekends to incorporate for traffic differences

EWhen Standard Deviation is higher the probability goes down and so the MPTS is worse

Answer : B

Question 6

BThe slope of the equation is a positive 130.5.

CThe predicted output Y is close to -18 when the Reactant level is set to 6.

DOver 85 % of the variation of the Energy Consumed is explained by the Reactant via this Linear Regression.

Answer : C, D
