Basic Statistics & Probability: Graph It to Me True or False

1. Two dice were rolled 50 times, and their sums were recorded in this bar graph.

Find the mode of the data.6.5

2. Two dice were rolled 50 times, and their sums were recorded in this bar graph.

Find the median of the data.6.5

3. Two dice were rolled 50 times, and their sums were recorded in this bar graph.

How does the theoretical probability of rolling a sum of 12 compare to the experimental probability?The experimental probability is higher.

4. This stem-and-leaf plot shows the scores from the last English test.

If a test is chosen at random, what is the probability that the score will be divisible by 4 AND greater than 80?≈ 80%

5. This stem-and-leaf plot shows the scores from the last English test.

If a test is chosen at random, what is the probability that the score will be divisible by 4 OR greater than 80?≈ 77%

6. This stem-and-leaf plot shows the scores from the last English test.

Find the mean, median, and mode of the stem-and-leaf plot. Round each answer to the nearest whole number.Mean = 82, median = 80, and mode = 81

7. 35 students took a test. This box-and-whisker plot shows the results.

What percentage of the students scored greater than 65 on the test?≈ 97%

8. 35 students took a test. This box-and-whisker plot shows the results.

If a score is chosen at random, what is the probability that it lies inside the box?50%

9. 35 students took a test. This box-and-whisker plot shows the results.

Based on this data, would a score of 48 be considered an outlier?I refuse to answer that question on the grounds that I don't know the answer.

10. Elana is growing a plant on her windowsill. Every week she records its height in inches. This scatter plot displays her findings, and a line of best fit is drawn. Based on this plot, how high can she expect the plant to be at 15 weeks?
