1. QuestionMultiple choice

What is the mean of 4, 6, 8, and 10?

Please select an answer first.

Correct answer: A

The correct answer is 77.

  1. Identify the information: Underline the quantities, relationships, or conditions given in the problem.
  2. Apply the strategy: The sum is 28 and there are 4 values, so the mean is 28 / 4 = 7.
  3. Check the result: Substitute the answer or review the units to make sure it fits the problem.

The sum is 28 and there are 4 values, so the mean is 28 / 4 = 7.

2. QuestionMultiple choice

What is the median of 3, 7, 9, 11, and 20?

Please select an answer first.

Correct answer: B

The correct answer is 99.

  1. Identify the information: Underline the quantities, relationships, or conditions given in the problem.
  2. Apply the strategy: The values are already ordered, and 9 is the middle value.
  3. Check the result: Substitute the answer or review the units to make sure it fits the problem.

The values are already ordered, and 9 is the middle value.

3. QuestionMultiple choice

What is the range of the data set 5, 9, 12, 18?

Please select an answer first.

Correct answer: C

The correct answer is 1313.

  1. Identify the information: Underline the quantities, relationships, or conditions given in the problem.
  2. Apply the strategy: Subtract the minimum from the maximum: 18 - 5 = 13.
  3. Check the result: Substitute the answer or review the units to make sure it fits the problem.

Subtract the minimum from the maximum: 18 - 5 = 13.

4. QuestionMultiple choice

A scatter plot shows that y generally increases as x increases. What type of association is shown?

Please select an answer first.

Correct answer: D

The correct answer is Positive association.

  1. Identify the information: Underline the quantities, relationships, or conditions given in the problem.
  2. Apply the strategy: When larger x-values tend to pair with larger y-values, the association is positive.
  3. Check the result: Substitute the answer or review the units to make sure it fits the problem.

When larger x-values tend to pair with larger y-values, the association is positive.

5. QuestionMultiple choice

Why is a random sample useful when studying the opinions of all students in a school?

Please select an answer first.

Correct answer: A

The correct answer is It can provide a representative group without surveying everyone.

  1. Identify the information: Underline the quantities, relationships, or conditions given in the problem.
  2. Apply the strategy: Random selection can produce a sample that represents the larger population.
  3. Check the result: Substitute the answer or review the units to make sure it fits the problem.

Random selection can produce a sample that represents the larger population.

6. QuestionMultiple choice

A bag contains 3 red marbles and 5 blue marbles. What is the probability of choosing a red marble?

Please select an answer first.

Correct answer: B

The correct answer is 38\frac{3}{8}.

  1. Identify the information: Underline the quantities, relationships, or conditions given in the problem.
  2. Apply the strategy: There are 3 favorable outcomes out of 8 total marbles.
  3. Check the result: Substitute the answer or review the units to make sure it fits the problem.

There are 3 favorable outcomes out of 8 total marbles.

7. QuestionMultiple choice

In an experiment, an event occurs 18 times in 30 trials. What is the experimental probability?

Please select an answer first.

Correct answer: C

The correct answer is 0.60.6.

  1. Identify the information: Underline the quantities, relationships, or conditions given in the problem.
  2. Apply the strategy: Divide successful trials by total trials: 18 / 30 = 0.6.
  3. Check the result: Substitute the answer or review the units to make sure it fits the problem.

Divide successful trials by total trials: 18 / 30 = 0.6.

8. QuestionMultiple choice

Which comparison best describes two data distributions?

Please select an answer first.

Correct answer: D

The correct answer is Compare their centers and spreads.

  1. Identify the information: Underline the quantities, relationships, or conditions given in the problem.
  2. Apply the strategy: Center and spread reveal how two distributions differ overall.
  3. Check the result: Substitute the answer or review the units to make sure it fits the problem.

Center and spread reveal how two distributions differ overall.

9. QuestionMultiple choice

A box plot has a first quartile of 6 and a third quartile of 14. What is the interquartile range?

Please select an answer first.

Correct answer: A

The correct answer is 88.

  1. Identify the information: Underline the quantities, relationships, or conditions given in the problem.
  2. Apply the strategy: The interquartile range is Q3 - Q1 = 14 - 6 = 8.
  3. Check the result: Substitute the answer or review the units to make sure it fits the problem.

The interquartile range is Q3 - Q1 = 14 - 6 = 8.

10. QuestionMultiple choice

What is the probability of getting heads on a fair coin and an even number on a fair six-sided die?

Please select an answer first.

Correct answer: B

The correct answer is 14\frac{1}{4}.

  1. Identify the information: Underline the quantities, relationships, or conditions given in the problem.
  2. Apply the strategy: The independent probabilities are 1/2 and 3/6 = 1/2; multiply them to get 1/4.
  3. Check the result: Substitute the answer or review the units to make sure it fits the problem.

The independent probabilities are 1/2 and 3/6 = 1/2; multiply them to get 1/4.
