Question: 3

There were 7 students enrolled in the Introduction to Artificial Intelligence course. These were the student's scores from the final exam: 64, 70, 80, 80, 90, 98, 100

What is the mean and mode for the outlined scores?

A83.14, 80

B79.84, 81.40

C80,80

D80, 83.14

Answer: A

Explanation:

The mean is the average of all the scores, which is found by adding them up and dividing by the number of scores. The mode is the most frequent score, which is the one that occurs the most times. To find the mean and mode for the outlined scores, we can use the following steps:

* Arrange the scores in ascending order: 64, 70, 80, 80, 90, 98, 100

* Add up the scores: 64 + 70 + 80 + 80 + 90 + 98 + 100 = 582

* Divide the sum by the number of scores: 582 / 7 = 83.14

* The mean is 83.14

* Count how many times each score occurs: 64 occurs once, 70 occurs once, 80 occurs twice, 90 occurs once, 98 occurs once, 100 occurs once

* The score that occurs the most times is 80

* The mode is 80

Therefore, the mean and mode for the outlined scores are 83.14 and 80, respectively12 Reference: 1: Mean, median, and mode review (article) | Khan Academy 2: Mean, Median, and Mode: Measures of Central Tendency - Statistics By Jim

Question: 4

The analytics team has been asked to provide an estimate of the number of customers they expect to have in 12 months. They debated how accurate that figure needs to be and determined that based on the availability of good data, they could predict within + or - 10%. This is an example of a:

AROM estimate

BDelphi estimate

CParametric estimate

DDefinitive estimate

Answer: A

Explanation:

A ROM estimate is a rough order of magnitude estimate that provides a quick and approximate estimate of the cost, time, or effort required for a project or a task. A ROM estimate is based on expert opinion or experience from past projects, and it usually has a large range of variation, such as + or - 10%. A ROM estimate is useful when there is limited information or data available, or when a high-level estimate is needed for planning or budgeting purposes. However, a ROM estimate also has a high degree of uncertainty and variability, and it should be refined as more details become available12 Reference: 1: Project Estimation Techniques Business Analysts Should Know About 2: Estimation techniques for business analysts -- The Functional BA

Question: 5

The analytics team is assessing the results of their analysis. They are surprised to find that their data indicates two events seem to

be strongly related even though the general belief in the organization is that they are independent of each other. Knowing that

this information will be used for decision making, they are concerned about presenting this dat

a. At an impasse, the business

analysis professional reminds them that the data can be presented as long as the team has:

AReview the results with management ahead of time and highlight any potential risk of using
this data

BConfidence that the correlation will reliably occur in the future and the risk of acting on this
is low

CFollowed all rules for data analysis endorsed as organizational standards so the risk of
acting on this is low

DThe ability to rerun the data analysis and the results are the same thereby minimizing the
risk of acting on this

Answer: D

Explanation:

The ability to rerun the data analysis and the results are the same is the condition that the team should have before presenting the data, because it is a technique that ensures the validity, reliability, and reproducibility of the data analysis. By rerunning the data analysis, the team can verify that the results are consistent and not affected by random errors, biases, or anomalies. The team can also confirm that the data analysis process is well-documented, transparent, and traceable, and that the results can be replicated by other analysts or stakeholders. This can minimize the risk of acting on the data, and increase the confidence and trust in the data analysis. Reference:
