  1. A scatter plot shows the number of hours studied vs. test scores for 10 students. The data points cluster near a line rising from left to right. What does this indicate?

    Answer: A positive correlation between study hours and scores

    A rising trend in a scatter plot indicates a positive correlation, meaning as study hours increase, test scores tend to increase.

  2. A bag contains 4 red, 3 blue, and 5 green marbles. If one marble is drawn at random, what is the probability it is NOT green?

    Answer: 7/12

    There are 4+3=7 non-green marbles out of 12 total, so P(not green) = 7/12.

  3. A frequency table shows: Science scores 60-69 (5 students), 70-79 (12 students), 80-89 (8 students), 90-99 (5 students). What percentage of students scored 80 or above?

    Answer: 37%

    Students scoring 80+ = 8+5=13 out of 30 total; 13/30 ≈ 43.3% rounds to 43%.

  4. A line graph shows monthly rainfall (in inches): Jan=2, Feb=1.5, Mar=3, Apr=4, May=5, Jun=2. What is the range of the rainfall data?

    Answer: 3.5 inches

    Range = maximum − minimum = 5 − 1.5 = 3.5 inches.

  5. Two fair six-sided dice are rolled. What is the probability that the sum equals 7?

    Answer: 1/6

    There are 6 ways to get a sum of 7 out of 36 possible outcomes, so probability = 6/36 = 1/6.

  6. A bar chart compares the production of four factories (A=200, B=350, C=150, D=300). Which factory produced exactly twice as much as Factory C?

    Answer: Factory B

    Factory C produced 150 units; twice that is 300, which equals Factory D's production.

  7. A data set has values: 12, 15, 15, 18, 20, 22, 22, 22, 25. What is the mode?

    Answer: 22

    The mode is the value that appears most frequently; 22 appears 3 times, more than any other value.
