Answer:
First choice:
- Most of the data in each plot are greater than 48.
Step-by-step explanation:
1. Boy's Heights.
Using the information you can create a frequency table:
Heigth Frequency
40 0
41 1
44 3
46 3
48 2
50 3
52 4
54 4
56 0
58 0
60 0
======
20 boys
2. Girl's Heights.
Similarly, create your frequency table:
Height Frequency
40 0
41 0
42 0
44 2
46 3
48 1
50 3
52 4
54 3
56 4
58 0
60 0
======
20 girls
Which is a true statement for most of the data in each plot?
Most of the data in each plot are greater than 48.
- Count the dots or add the frequencies from the tables.
- For boys, the frequency of points greater than 48 is: 3 + 4 + 4 = 11 which is more than half (there are 20 dots).
- For girls, the frequency of points greater than 48 is: 3 + 4 + 3 + 4 = 14, which is also more than half.
Hence, it is correct that most fo the data in each plot are greater than 48.
