A. 12;21;18.4 ***
B. 12; 18.4; 21
C. 39; 21; 18.4
D. 39; 18.4; 21
C is correct
rip still looking for answer </3
1. Mean = -29.1, median = -28.5, mode = -49, range = 40
2. 39; 21; 18.4
3. Walked is 7, biked is 6, bus is 5, family car is 3, car pool is 3
4. 23, 24, 24, 24, 26, 26, 27, 28, 28, 30 on a line plot
5. C, 5 | 2
6 | 4 7
7 | 4 6
8 | 1 7 9
9 | 3
10 | 8
11 | 4
6. Median for Team 1: 15 Median for Team 2: 14
7. 74 as minimum, 81 as lower quartile, 89 as median, 92 as upper quartile, 97 as maximum on box and whisker plot
8. 30 as minimum, 33 as lower quartile, 40 as median, 49 as upper quartile, 57 as maximum on box and whisker plots
9. About 50% scored higher; about 50% scored lower
10. A, look for the one that has two that looked merged together around 8.4 and 8.6 on the right
11. No trend; the number of pets owned and the owner’s height
12: (5, 7.4)
13. 375
14. 2 stamps
15. 172 for circle graph of central angle for the group that plans on running for student government next year
16. 15, for how many people chose chocolate chip cookies
17. 30%, for what percentage of the children chose peanut butter
18. D, the scatter plot where it looks like all the dots are scatter around everywhere
19. Ration number allows whole, fractions or decimals, irrational number are number that cannot be turned into a fraction, so diagram A, where they’re both separate from each other
Part 2 of the quiz, find the mean absolute deviation of the students height, the answer is 3.8 because…
59 + 71 + 68 + 75 + 67 = 360, you divide by 5 because that’s how many number we have, 360 divided by 5 is 68
59 - 68 = |-9| = 9
71- 68 = |3| = 3
68 - 68 = |0| = 0
75 - 68 = |7| = 7
67 - 68 = |1| = 1
Add up the new number you have
9 + 3 + 0 + 7 + 1 = 19 and you’re gonna divide it by 5 because that’s how many number we have, so, 19 divided by 5 is 3.8 and that is your answer, hope this helps, remember everyone’s test is different but this should help.
