The Alpha level of a test (level of significance) represents the yardstick against which P-values are measured and the Null Hypothesis is rejected if the P-value is which of these?

Greater than the Beta and Alpha level.

Less than the power of one minus Beta.

Contingency Tables are used to perform which of these functions?

Compare more than two sample proportions with each other

Illustrate one-tail proportions

Contrast the Outliers under the tail

Compare more than two sample proportions with each other

For the data shown here a Belt suspects the three grades are supplying the same results. Which statement(s) are true for proper Hypothesis Testing?

An appropriate test to test Central Tendency is the Mood's Median test

The most appropriate Central Tendency to test is the Means

An appropriate test to test Central Tendency is the Levene's test

An appropriate test to test Central Tendency is the ANOVA test

An appropriate test to test Central Tendency is the Mood's Median test

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 ____________?

Reduce average commute time to work by departing earlier

Increase the average time of commute

Maintain the average time of commute and change route to work

Reduce average commute time to work by departing earlier

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

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

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

It does not require data to come from Normally Distributed populations

They look at the Median rather than the Mean of populations

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

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

It does not require data to come from Normally Distributed populations

They look at the Median rather than the Mean of populations

When there are no parameters to measure in the process

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?

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

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

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

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

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

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

When it comes to Control one of the most effective means of eliminating defects is to _________________ .
