QUESTION 74

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?

 

A.

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

B.

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

C.

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

D.

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

E.

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

 

Correct Answer: B

 

 

QUESTION 75

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 ___________?

 

A.

1 minute

B.

6 minutes

QUESTION 77

According to a manager it takes an average week

day 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 ____________?

 

A.

Increase the average time of commute

B.

Maintain the average time of commute and change route to work

C.

Reduce average commute time to work by departing earlier

D.

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

 

Correct Answer: C

Non-parametric testing is done when which of these are applicable? (Note: There are 3 correct answers).

 

A.

When the traditional t tests don’t produce the results we need

A Hypothesis Test for the Median of the population is in question

C.

It does not require data to come from Normally Distributed populations

D.

They look at the Median rather than the Mean of populations

E.

When there are no parameters to measure in the process

 

Correct Answer: BCD

 

 

QUESTION 79

The Mann-Whitney Test is used to test if the Means for two samples are different.

 

A.

True
