1. QuestionMultiple choice

What is the mean of 8,10,12,14,168,10,12,14,16?

Please select an answer first.

Correct answer: A

The correct answer is 1212.

  1. Identify the quantities and operation: Read the numbers, units, model, table, or diagram carefully and identify what the problem asks you to find.
  2. Use a math strategy: The sum is 60. Divide by 5 values to get a mean of 12.
  3. Check the result: Compare the result with the choices and check whether it is reasonable. The correct answer is 1212.

The sum is 60. Divide by 5 values to get a mean of 12.

2. QuestionMultiple choice

A scatter plot rises from left to right. What type of association does it show?

Please select an answer first.

Correct answer: B

The correct answer is A positive association.

  1. Identify the quantities and operation: Read the numbers, units, model, table, or diagram carefully and identify what the problem asks you to find.
  2. Use a math strategy: When y tends to increase as x increases, the association is positive.
  3. Check the result: Compare the result with the choices and check whether it is reasonable. The correct answer is A positive association.

When y tends to increase as x increases, the association is positive.

3. QuestionMultiple choice

A line of best fit is y=2x+5y=2x+5. What value does it predict when x equals 6?

Please select an answer first.

Correct answer: C

The correct answer is 1717.

  1. Identify the quantities and operation: Read the numbers, units, model, table, or diagram carefully and identify what the problem asks you to find.
  2. Use a math strategy: Substitute 6: y = 2 times 6 + 5 = 17.
  3. Check the result: Compare the result with the choices and check whether it is reasonable. The correct answer is 1717.

Substitute 6: y = 2 times 6 + 5 = 17.

4. QuestionMultiple choice

A two-way table shows 12 students in band, 8 of whom play sports. What is the probability that a randomly selected band student plays sports?

Please select an answer first.

Correct answer: D

The correct answer is 2/32/3.

  1. Identify the quantities and operation: Read the numbers, units, model, table, or diagram carefully and identify what the problem asks you to find.
  2. Use a math strategy: The conditional probability is 8 out of 12, which simplifies to 2/3.
  3. Check the result: Compare the result with the choices and check whether it is reasonable. The correct answer is 2/32/3.

The conditional probability is 8 out of 12, which simplifies to 2/3.

5. QuestionMultiple choice

Why should a survey about school transportation use a random sample of students?

Please select an answer first.

Correct answer: A

The correct answer is To give students in the population a fair chance of being selected..

  1. Identify the quantities and operation: Read the numbers, units, model, table, or diagram carefully and identify what the problem asks you to find.
  2. Use a math strategy: Random selection reduces selection bias and makes the sample more useful for describing the population.
  3. Check the result: Compare the result with the choices and check whether it is reasonable. The correct answer is To give students in the population a fair chance of being selected..

Random selection reduces selection bias and makes the sample more useful for describing the population.

6. QuestionMultiple choice

A data set has a median of 18 and a mean of 25. Which statement is most reasonable?

Please select an answer first.

Correct answer: B

The correct answer is A high value may be pulling the mean upward..

  1. Identify the quantities and operation: Read the numbers, units, model, table, or diagram carefully and identify what the problem asks you to find.
  2. Use a math strategy: When the mean is greater than the median, one or more high values may pull the mean upward.
  3. Check the result: Compare the result with the choices and check whether it is reasonable. The correct answer is A high value may be pulling the mean upward..

When the mean is greater than the median, one or more high values may pull the mean upward.

7. QuestionMultiple choice

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

Please select an answer first.

Correct answer: C

The correct answer is 3/103/10.

  2. Use a math strategy: The probability is 3/5 for red, then 2/4 for blue. Multiply to get 6/20 = 3/10.
  3. Check the result: Compare the result with the choices and check whether it is reasonable. The correct answer is 3/103/10.

The probability is 3/5 for red, then 2/4 for blue. Multiply to get 6/20 = 3/10.

8. QuestionMultiple choice

A model predicts 18 visitors, but 21 visitors arrive. What is the residual defined as actual minus predicted?

Please select an answer first.

Correct answer: D

The correct answer is 33.

  1. Identify the quantities and operation: Read the numbers, units, model, table, or diagram carefully and identify what the problem asks you to find.
  2. Use a math strategy: Subtract predicted from actual: 21 - 18 = 3.
  3. Check the result: Compare the result with the choices and check whether it is reasonable. The correct answer is 33.

Subtract predicted from actual: 21 - 18 = 3.

9. QuestionMultiple choice

Two data sets have the same mean. Set A has a smaller spread than Set B. What does this mean?

Please select an answer first.

Correct answer: A

The correct answer is Set A values are clustered more closely around the mean..

  1. Identify the quantities and operation: Read the numbers, units, model, table, or diagram carefully and identify what the problem asks you to find.
  2. Use a math strategy: A smaller spread means the values tend to lie closer to their center than the values in Set B.
  3. Check the result: Compare the result with the choices and check whether it is reasonable. The correct answer is Set A values are clustered more closely around the mean..

A smaller spread means the values tend to lie closer to their center than the values in Set B.

10. QuestionMultiple choice

A fair spinner has 4 equal sections labeled 1, 2, 3, and 4. What is the probability of landing on an even number?

Please select an answer first.

Correct answer: B

The correct answer is 1/21/2.

  1. Identify the quantities and operation: Read the numbers, units, model, table, or diagram carefully and identify what the problem asks you to find.
  2. Use a math strategy: Two of the four equally likely outcomes, 2 and 4, are even, so the probability is 2/4 = 1/2.
  3. Check the result: Compare the result with the choices and check whether it is reasonable. The correct answer is 1/21/2.

Two of the four equally likely outcomes, 2 and 4, are even, so the probability is 2/4 = 1/2.
