Answer 1

Explanation:

Part A

There are 25 students in the class, and the least number of brothers or sisters is 0, so the least data value on the line plot should be 0. The greatest number of brothers or sisters is 4, so the greatest data value on the line plot should be 4.

Part B

There are 7 students with 2 brothers or sisters, so there will be 7 dots above 2. There are 4 students with 1 brother or sister, so there will be 4 dots above 1. There are 6 students with 3 brothers or sisters, so there will be 6 dots above 3. There are 3 students with 4 brothers or sisters, so there will be 3 dots above 4.

Therefore, the correct answers are:

Least data value: 0

Greatest data value: 4

Dots above 1: 4

Dots above 4: 7

Dots above 3: 6
