  1. The test scores of 5 students are 72, 85, 90, 68, and 80. What is the mean score?

    Answer: 79

    Mean = (72 + 85 + 90 + 68 + 80) ÷ 5 = 395 ÷ 5 = 79.

  2. The ages of 7 people are: 14, 22, 17, 22, 31, 19, 22. What is the mode?

    Answer: 22

    22 appears three times, which is more than any other value, making it the mode.

  3. A bag contains 3 red, 5 blue, and 2 green marbles. What is the probability of randomly drawing a green marble?

    Answer: 1/5

    P(green) = 2 ÷ 10 = 1/5.

  4. What is the median of the data set {3, 7, 9, 12, 15}?

    Answer: 9

    The data is already ordered; the middle (third) value is 9.

  5. A student scored 78, 85, and 91 on three tests. What score on the fourth test gives an average of exactly 85?

    Answer: 86

    Target total = 85 × 4 = 340; fourth score = 340 − (78 + 85 + 91) = 340 − 254 = 86.

  6. A spinner has 8 equal sections numbered 1 through 8. What is the probability of landing on an even number?

    Answer: 1/2

    There are 4 even numbers (2, 4, 6, 8) out of 8 sections, so P = 4/8 = 1/2.

  7. What is the range of the data set {4, 11, 7, 3, 15, 9}?

    Answer: 12

    Range = maximum − minimum = 15 − 3 = 12.
