which statement does the data support

What are your choices?

To find out which statement the data supports, let's analyze the given ages of the 9 grandchildren: 1, 15, 9, 12, 18, 9, 5, 14, and 7.

Statement options could be something like:

1. "The majority of the grandchildren are older than 10 years old."
2. "There are more grandchildren who are younger than 10 years old."
3. "There is an equal number of grandchildren under and over 10 years old."
4. "The range of the grandchildren's ages is less than 10 years."
5. "The range of the grandchildren's ages is more than 10 years."

To find which statement the data supports, we need to evaluate the ages of the grandchildren.

Sorting the ages in ascending order, we have: 1, 5, 7, 9, 9, 12, 14, 15, 18.

From this sorted list, we can make the following observations:

1. There are two grandchildren younger than 10: 1 and 5.
2. There are six grandchildren equal to or older than 10: 7, 9, 9, 12, 14, and 15.
3. The range of the grandchildren's ages is 18 - 1 = 17, which is more than 10.

Based on this analysis, we can conclude that the statement supported by the data is:

"There are more grandchildren who are younger than 10 years old."
