Step-by-step explanation:
1) Find the Mean of 7 18 9 22 4.
7 + 18 + 9 + 22 + 4 = 50
50 ÷ 5 = 10
2) Find the Median of 7 18 9 22 4.
4 7 9 18 22
The Median is 9.
3) Find the Mean of 7 3 7 4 8 9 2.
7 + 3 + 7 + 4 + 8 + 9 + 2 = 40
40 ÷ 7 = 5.7
4) Find the Median of 7 3 7 4 8 9 2.
2 3 4 7 7 8 9
The Median is 7.
5) Find the Mode of 7 3 7 4 8 9 2.
Mode is the number that occurs the most.
2 3 4 7 7 8 9
The Mode is 7.
6) Find the Median of 6 10 23 24 13 9 23 12.
6 9 10 12 13 22 23 24
There are 8 numbers in this set of numbers, so the Median is the average of the two numbers in the middle. So,
The Median is 12.5.
7) Find the Mean of 6 10 23 24 13 9 23 12.
6 + 10 + 23 + 24 + 13 + 9 + 23 + 12 = 120
120 ÷ 8 = 15
The Mean is 15.
8) Find the Median of 120 113 101 101 112.
101 101 112 113 120
The Median is 112.
9) Find the Mean of 73 72 72 98 99 96 98 98 73.
73 + 72 + 72 + 98 + 99 + 96 + 98 + 98 + 73 = 779
779 ÷ 9 = 86.6.
10) Find the Mode of 73 72 72 98 99 96 98 98 73.
72 72 73 73 96 98 98 98 99
The Mode is 98.
11) Find the Mode of 6 10 23 24 22 9 23 13.
6 9 10 13 22 23 23 24
The Mode is 23.
12) Find the Median of 73 72 72 98 99 96 98 98 73.
72 72 73 73 96 98 98 98 99
The Median is 96.
13) Find the Median of 12 22 26 15 18 22 29 11 22 18.
11 12 15 18 18 22 22 22 26 29
There are 10 numbers in this set of numbers, so the Median is the average of the two numbers in the middle. So,
The Median is 20.

Answer:
The frequency of oranges is the classroom is 47.37%.
Step-by-step explanation:
The relative frequency of oranges is the number of oranges divided by the total number of fruits.
We have that:
8 students brought 2 apples each. So there are 8*2 = 16 apples
4 students brought an apple and an orange each. So there are 16 + 4*1 = 20 apples and 4*1 = 4 oranges.
7 students brough 2 oranges each. So there are 4 + 2*7 = 18 oranges.
There are 18 oranges, and 20+18 = 38 fruits in total.
So the frequency of oranges in the classrom is
