1. Read All Questions Carefully: Make sure you understand each question.
2. Time Management: You have a specific amount of time to complete the exam.
Keep an eye on the clock and pace yourself.
3. Allowed Materials: Only use materials that are explicitly allowed. Unauthorized
materials can lead to disqualification.
4. ANS Format: Follow the required format for your ANS. For example, multiple-choice
questions might need you to select the best ANS, while essay questions require
detailed responses.
5. Academic Integrity: Adhere to the university's honor code. Any form of cheating or
plagiarism is strictly prohibited.
6. Technical Requirements: Ensure your computer and internet connection are
stable. For online exams, you might need a webcam and microphone for proctoring

,1. Which statistical method is most appropriate for predicting a
dependent variable based on one independent variable?
- A) Multiple Regression
- B) Simple Linear Regression
- C) Logistic Regression
- D) ANOVA
ANS: B) Simple Linear Regression
Rationale: Simple linear regression is used to predict the
value of a dependent variable based on the value of a single
independent variable.
2. What is the primary purpose of conducting a time series
analysis in business?
- A) To determine causation between variables
- B) To evaluate past performance only
- C) To forecast future trends
- D) To analyze cross-sectional data
ANS: C) To forecast future trends

, 3. Which of the following assumptions is NOT required for the
application of the chi-square test?
- A) Data must be nominal
- B) Observations must be independent
- C) Population variance is known
- D) Sample size should be sufficiently large
ANS: C) Population variance is known
Rationale: The chi-square test does not depend on knowledge
of population variance; it requires categorical data and large
sample sizes for validity.
4. In hypothesis testing, which type of error occurs when a true
null hypothesis is rejected?
- A) Type I error
- B) Type II error
- C) Sampling error
- D) Measurement error
ANS: A) Type I error
Rationale: A Type I error occurs when a true null hypothesis
is incorrectly rejected.
