1. QuestionMultiple choice

A scatter plot shows that as study time increases, quiz scores generally increase. What association is shown?

Please select an answer first.

Correct answer: A

The correct answer is A positive association.

  1. Identify the math idea: Decide whether the question uses linear relationships, numbers, expressions, equations, geometry, statistics, probability, or problem solving.
  2. Show the reasoning: Both variables tend to increase together, which is a positive association.
  3. Check the result: Review the sign, units, operation, and estimate to make sure the answer is reasonable.

Both variables tend to increase together, which is a positive association.

2. QuestionMultiple choice

A line of fit is y=4x+6y = 4x + 6. What value does it predict for x=5x = 5?

Please select an answer first.

Correct answer: B

The correct answer is 2626.

  1. Identify the math idea: Decide whether the question uses linear relationships, numbers, expressions, equations, geometry, statistics, probability, or problem solving.
  2. Show the reasoning: Substitute 5: y = 4(5) + 6 = 26.
  3. Check the result: Review the sign, units, operation, and estimate to make sure the answer is reasonable.

Substitute 5: y = 4(5) + 6 = 26.

3. QuestionMultiple choice

In a two-way table, 18 of 30 students who participate in music also play a sport. What is the conditional probability of playing a sport given music participation?

Please select an answer first.

Correct answer: C

The correct answer is 35\frac{3}{5}.

  1. Identify the math idea: Decide whether the question uses linear relationships, numbers, expressions, equations, geometry, statistics, probability, or problem solving.
  2. Show the reasoning: The relevant group has 18 sport players out of 30 music participants: 18/30 = 3/5.
  3. Check the result: Review the sign, units, operation, and estimate to make sure the answer is reasonable.

The relevant group has 18 sport players out of 30 music participants: 18/30 = 3/5.

4. QuestionMultiple choice

A bag has 3 red tiles and 2 blue tiles. What is the probability of selecting red and then blue without replacement?

Please select an answer first.

Correct answer: D

The correct answer is 310\frac{3}{10}.

  1. Identify the math idea: Decide whether the question uses linear relationships, numbers, expressions, equations, geometry, statistics, probability, or problem solving.
  2. Show the reasoning: The probability is 3/5 for red, followed by 2/4 for blue: 3/5 × 2/4 = 3/10.
  3. Check the result: Review the sign, units, operation, and estimate to make sure the answer is reasonable.

The probability is 3/5 for red, followed by 2/4 for blue: 3/5 × 2/4 = 3/10.

5. QuestionMultiple choice

Which sample is most likely biased?

Please select an answer first.

Correct answer: A

The correct answer is Asking only students on the basketball team which sport should receive more funding.

  1. Identify the math idea: Decide whether the question uses linear relationships, numbers, expressions, equations, geometry, statistics, probability, or problem solving.
  2. Show the reasoning: The basketball-team sample is unlikely to represent students with different interests.
  3. Check the result: Review the sign, units, operation, and estimate to make sure the answer is reasonable.

The basketball-team sample is unlikely to represent students with different interests.

6. QuestionMultiple choice

A spinner is used 50 times and lands on green 18 times. What is the experimental probability of green?

Please select an answer first.

Correct answer: B

The correct answer is 925\frac{9}{25}.

  1. Identify the math idea: Decide whether the question uses linear relationships, numbers, expressions, equations, geometry, statistics, probability, or problem solving.
  2. Show the reasoning: The experimental probability is 18/50, which simplifies to 9/25.
  3. Check the result: Review the sign, units, operation, and estimate to make sure the answer is reasonable.

The experimental probability is 18/50, which simplifies to 9/25.

7. QuestionMultiple choice

Which statistic is most affected by one extremely large outlier?

Please select an answer first.

Correct answer: C

The correct answer is The mean.

  1. Identify the math idea: Decide whether the question uses linear relationships, numbers, expressions, equations, geometry, statistics, probability, or problem solving.
  2. Show the reasoning: The mean uses every value in the calculation, so an extreme value can pull it toward the outlier.
  3. Check the result: Review the sign, units, operation, and estimate to make sure the answer is reasonable.

The mean uses every value in the calculation, so an extreme value can pull it toward the outlier.

8. QuestionMultiple choice

A survey finds that 24 of 60 participants prefer a new bus route. What relative frequency estimates the preference?

Please select an answer first.

Correct answer: D

The correct answer is 0.40.4.

  1. Identify the math idea: Decide whether the question uses linear relationships, numbers, expressions, equations, geometry, statistics, probability, or problem solving.
  2. Show the reasoning: Divide 24 by 60: 24/60 = 0.4.
  3. Check the result: Review the sign, units, operation, and estimate to make sure the answer is reasonable.

Divide 24 by 60: 24/60 = 0.4.

9. QuestionMultiple choice

If the probability of rain is 0.72, what is the probability that it will not rain?

Please select an answer first.

Correct answer: A

The correct answer is 0.280.28.

  1. Identify the math idea: Decide whether the question uses linear relationships, numbers, expressions, equations, geometry, statistics, probability, or problem solving.
  2. Show the reasoning: Use the complement: 1 − 0.72 = 0.28.
  3. Check the result: Review the sign, units, operation, and estimate to make sure the answer is reasonable.

Use the complement: 1 − 0.72 = 0.28.

10. QuestionMultiple choice

A data set has a first quartile of 8 and a third quartile of 17. What is the interquartile range?

Please select an answer first.

Correct answer: B

The correct answer is 99.

  1. Identify the math idea: Decide whether the question uses linear relationships, numbers, expressions, equations, geometry, statistics, probability, or problem solving.
  2. Show the reasoning: Subtract the first quartile from the third quartile: 17 − 8 = 9.
  3. Check the result: Review the sign, units, operation, and estimate to make sure the answer is reasonable.

Subtract the first quartile from the third quartile: 17 − 8 = 9.
