  1. What is the mean of: 4, 8, 6, 10, 2?

    Answer: 6

    Mean = sum ÷ count = (4 + 8 + 6 + 10 + 2) ÷ 5 = 30 ÷ 5 = 6.

  2. What is the median of: 3, 7, 1, 9, 5?

    Answer: 5

    Arrange in order: 1, 3, 5, 7, 9. The middle value (3rd of 5) is 5.

  3. A bag has 3 red and 7 blue balls. What is the probability of picking a red ball?

    Answer: 3/10

    Probability = favorable outcomes ÷ total outcomes = 3 ÷ (3 + 7) = 3/10.

  4. What is the standard deviation a measure of?

    Answer: Spread or variability in data

    Standard deviation measures the spread or dispersion of data around the mean. A larger standard deviation indicates more variability in the data set.

  5. In a normal distribution, approximately what percentage of data falls within one standard deviation of the mean?

    Answer: 68%

    In a normal distribution, approximately 68% of data falls within one standard deviation of the mean. This is part of the 68-95-99.7 empirical rule.

  6. If P(A) = 0.4 and P(B) = 0.3 and A and B are independent, what is P(A and B)?

    Answer: 0.12

    For independent events, P(A and B) = P(A) × P(B) = 0.4 × 0.3 = 0.12.
