Isaac flipped a coin 5 times. The table shows his results.

If Isaac continues to flip the coin, which statement will be true?

• A. The experimental probability will get closer to the theoretical probability.

• B. The theoretical probability will get closer to the experimental probability.

Use the circle graph and histogram below to answer the question. Which of the following statements is NOT true?

• A. Both graphs have the same intervals.

• B. Both graphs show the exact range of data.

• C. Neither graph shows the exact mean.

• D. Neither graph shows the exact median.

How would changing the interval size impact the representation of data?

• A. When the intervals are smaller, there are fewer bins.

• B. When the intervals are larger, there are more bins.

• C. When the intervals are smaller, it's harder to see the shape of the data and draw conclusions.
