    3. Eliminate bugs
    4. Improve hardware performance
  4. How does storytelling enhance the communication of data insights?
    1. By focusing solely on statistical analysis
    2. By using visuals and narrative to make data relatable and engaging
    3. By ignoring complex data patterns
    4. . By minimizing the use of charts and graphs
  5. Functional programming supports:
    1. Sequential processing
    2. Parallel and concurrent programming
    3. Random execution

    2. False null hypothesis is not rejected
    3. Random data used
    4. P-value too small
  7. The try-except block is used for:
    1. File creation
    2. Error handling
    3. Data sorting
    4. Data merging
  8. Power of a test means:
    1. Energy use of computer
    2. Its ability to detect an effect when it exists
    3. Sample size
    4. Significance level
  9. The term “programming paradigm” refers to:
    1. Coding language

    2. stop()
    3. close()
    4. quit()
  12. Why is it important to use visuals effectively in hypotheses testing?
    1. To replace the need for statistical analysis
    2. To present data in a more understandable manner and enhance communication
    3. To make the data collection process easier
    4. To avoid need of a hypothesis formulation

Q3. Long questions (Attempt any 3 of 4 · 3 × 4 = 12)

  1. Write a Python program highlighting the use of functions to simplify a problem.For example, create a program that calculates the average of a list of numbers and by using separate functions to add and without repeating values.
  2. Discuss the challenges in ensuring data accuracy and relevance in a data story. How can these challenges be addressed to improve the credibility of the data story?
  3. Create a Python dictionary to store student names as keys and their grades as values.Write a program to add new students, update existing students’ grades, and remove students from the dictionary.
  4. Evaluate how feedback can be used to refine data storytelling techniques. Provide examples of how constructive criticism can lead to more effective data presentations.
