Answer 1

There were 32 middle school students between 11 and 13 years inclusive.

Step-by-step explanation:

To find the number of students between 11 and 13 years inclusive, we need to count how many ages in the given data fall within that range. Looking at the list of ages, we can see that the ages 11, 12, and 13 are present. Counting the frequency of these ages, we have:

• Age 11: 7 students
• Age 12: 11 students
• Age 13: 14 students

Adding up these frequencies, we have 7 + 11 + 14 = 32. Therefore, there were 32 middle school students between 11 and 13 years inclusive.
