    • C.
      Hire a large team of specialists and start building before any use case is defined
    • D.

    Show answer

    Correct answer:

    • B.
      Assess business priorities, data assets, and capability gaps before choosing tools

    Explanation

    Strategy starts from the business priorities the analytics program must serve and an honest view of the data and skills available. Choosing a framework, hiring before use cases exist, or launching many pilots at once all put tools and activity ahead of purpose.
  2. Question 2
    A p-value below 0.05 proves that the alternative hypothesis is true.
    • A.
      True
    • B.
      False
    Show answer

    Correct answer:

    • B.
      False

    Explanation

    A p-value is the probability of data at least as extreme as those observed, assuming the null hypothesis is true. It does not prove the alternative, and it says nothing about the size or practical importance of an effect. The statement is false.
