  2. Please select a Team. 1. 2. 3. 4. 5. • Nemo • Dory • Bruce • Squirt • Jacques

  3. 1. Which five number summary could be used to create a box-and-whisker plot for the data below:0, 12, 5, 13, 8, 7, 9, 10, 4, 5 • 0, 5, 7.5, 10, 13 • 0, 5, 5, 8.5, 10 • 4, 5, 8, 11, 13 • 0, 4, 8, 12, 13 Response Grid

  4. 2. Which of the following is not true about the interquartile range for Worker A and Worker B? • The interquartile range contains the middle 50% of the data values. • Worker A’s interquartile range is calculated as 200 – 125 = 75 • The interquartile range is equal to the difference between the median and 1st quartile. • Worker B’s interquartile range is calculated as 175 – 100 = 75 Response Grid

  5. Team Scores

  6. 3. A teacher asked students in one class to record how tall they are on cm. He compared the data for the girls and the boys in the box plots shown below. What is the teacher’s conclusion for all his students, based on the data in the box plots? • The boys are all taller than the girls. • The median height of the boys is greater than the median height of the girls. • The range of the girls heights is smaller that the range of the boys heights. • The maximum height of the girls is the same as the maximum height of the boys. Response Grid

  7. 4. Which data set has a MAD (mean absolute deviation) of 10? • 90, 75, 85, 100, 80 • 100, 90, 65, 90, 100 • 70, 80, 95, 100, 85 • 95, 100, 75, 80, 75 Response Grid

  9. 5. Representative samples of populations can BEST be obtained through . . . • Convenience Sampling • Systematic Sampling • Random Sampling • Voluntary-Response Sampling Response Grid

  10. Participant Scores

  11. 6. In a random sample, 200 students are surveyed from a school population of 1,200 students to determine how many students watch Duck Dynasty. Which statement about the random sample is not correct. • One sixth of the students in the population were sampled. • One out of every six students in the population was sampled. • 17% of the students in the population were sampled. • The ratio of students sampled to those not sampled is 200 to 1,200. Response Grid

  13. What percentage of your current points would you like to wager on the next question? • 0% 25% 50% 75% 100%

  14. 7. 30 of the 200 students in the previous questions said they watch Duck Dynasty. Based on this information, about how many students in the school watch the show? • 180 • 300 • 360 • 800 Response Grid

  15. Team Scores

  16. 8. Emily’s math test scores for the semester are: 94, 95, 98, 80, 74, and 78. If her teacher drops her lowest score, what will happen to the mean? • It will stay the same • It will be lower than the original mean • It will be higher than the original mean • The relationship cannot be determined Response Grid

  17. Participant Scores

  18. 9. What is the approximate interquartile range for Carl’s sales? • 30 • 15 • 58 • 23 Response Grid

  19. Team Scores

  20. 10. Which of the following best describes mean absolute deviation? • The absolute value of the data set • The absolute value of the sum of the data set • The average distance each value is from the mean • The distance between the maximum and minimum values Response Grid

  21. Team Scores

  22. 11. The scoring totals for each player on the school basketball team are listed below. What is the mean absolute deviation of the scores?10, 7, 6, 3, 11, 15, 8, 4 • 3 • 7.5 • 8 • 24 Response Grid

  23. Team Scores

  24. What percentage of your current points would you like to wager on the final question? • 0% 25% 50% 75% 100%

  25. 12. Timmy created a random sample of 50 girls and 50 boys at his school. He found the mean height of girls to be 60 inches and the boys to be 58 inches. He printed his results in the school newspaper stating that “on average, the girls in this school are taller than the boys!” Which statement best fits this situation? • The sample size Timmy used was very small so the inferences made from the data may not be valid. • The girls in Timmy’s school are on average 2 inches taller than the boys. • Timmy used random sampling so the results must be valid. • Answer not given.
