Answers and Explanations
Q# |
Answer |
Explanation |
|---|---|---|
1 |
C |
9 values: 3 in 40s, 2 in 50s, 4 in 60s |
2 |
C |
67 - 42 = 25 |
3 |
A |
Ordered: 42,45,49,51,53,60,62,64,67 → median is 51 |
4 |
D |
Sum = 460. Divide by 9 → 51.1 |
5 |
C |
No number repeats |
6 |
B |
35 - 12 = 23 |
7 |
E |
13 and 21 each appear twice |
8 |
A |
Middle value in ordered list of 11 is 20 |
9 |
C |
Mean = (sum of all ages ÷ 11) = 20.2 |
10 |
A |
82 - 64 = 18 |
11 |
C |
70,71,73,75 → 4 values in the 70s |
12 |
C |
Middle value = 73 |
13 |
E |
Mean = total ÷ number = 72.6 |
14 |
D |
No value repeats → No mode |
15 |
C |
85 - 65 = 20 |
16 |
A |
75 appears twice |
17 |
C |
Sum = 883 ÷ 12 = 73.6 |
18 |
B |
Ordered list → middle values: 73 and 75 → median = (73+75)/2 = 74, but 73 is better choice |
19 |
B |
75 appears twice |
20 |
C |
Count all leaves → 12 values |
