GUIDE 2026 FULL QUESTIONS AND
SOLUTIONS GRADED A+
◍ Step 1 of the decision-making model.
Answer: identify the problem
◍ Decisions under risk.
Answer: There are several different outcomes that can occur with a given
alternative, and decision makers know the probability or likelihood of each
potential alternative outcome.
◍ Correlation that occurs when one variable increases and the other variable
increases too.
Answer: Positive correlation
◍ Measurement used to gauge performance.
Answer: metric
◍ Subjective questioning.
Answer: uses open-ended answers.
◍ A payoff table.
Answer: is similar to a decision tree but uses a table instead of the graphical
representation. All of the alternatives are listed on the left side of the table
and all of the possible states of nature are listed across the top.
◍ Measurable data often obtained through observations or testing.
Answer: objective data
◍ The analysis of data to describe, interpret, and summarize data in a
, meaningful way to find patterns.
Answer: descriptive statistics
◍ What would be the best reason for not wanting to use quantitative analysis?.
Answer: When the problem being evaluated lacks the presence of objective,
valid, reliable, and measurable data to use for the analysis.
◍ Program Evaluation and Review Technique (PERT).
Answer: uses a statistical distribution called the beta distribution. This is
sometimes referred to as the three-point estimation.
◍ Network diagrams.
Answer: help plan, schedule, and control complex projects.
◍ Tool that can be used to visualize important aspects of a problem.
Answer: decision tree
◍ Surveys are one method of data collection and are always done face to face..
Answer: False
◍ When would a business forecast tend to be the most accurate?.
Answer: The time nearest the period under study.
◍ Three specific time estimates are used in the beta distribution calculation:.
Answer: Optimistic -The best case scenario, or minimum length of time, to
complete an activity. Let A stand for Optimistic.Most likely - The duration
of an activity given a normal level of effort and performance under normal
working conditions. Since this time estimate is the most likely to occur, it is
the mode of the beta distribution. Let M stand for Most Likely.Pessimistic -
The worst case scenario, or maximum length of time, to complete an
activity. Let P stand for Pessimistic.
◍ Expected Monetary Value Analysis.
Answer: is a statistical tool to calculate an average outcome when the future
outcomes have several scenarios that might happen.
◍ Variable that changes the effect of independent variable on the dependent
variable.
, Answer: moderating variable
◍ The number that occurs most often in a set of numbers.
Answer: mode
◍ Would a quantitative or qualitative method be used for the following? The
comic is interested in how funny his new jokes are to a new audience..
Answer: Qualitative
◍ Steps in Quantitative Analysis.
Answer: 1. Define problem2. Develop mathematical model3. Prepare and
input data4. Find best solution5. Test solution6. Analyze results7.
Implement solution
◍ Open-ended questions.
Answer: questions that do not offer answer choices but instead encourage a
narrative response.
◍ Safety stock.
Answer: ensures that a business will not run out of inventory when the
demand is unusually high.
◍ feasible area.
Answer: area "common" to both constraints
◍ Crash cost shortcut (this will give you the cost of the maximum time
reduction) divide by the number of maximum reduction days to calculate the
cost per day.
Answer: Crash cost - Normal cost
◍ The Critical Path Method (CPM) is a preferred method by many managers.
Answer: This method will require determining the task'sEarliest start time
(ES) - The earliest an activity can start without starting before any
predecessor activities.Earliest finish time (EF) - The earliest an activity can
finish.Latest start time (LS) - The latest time an activity can start without
delaying the entire project.Latest finish time (LF) - The latest time an
activity can finish without delaying the entire project.
