Solution

Solution Steps

To find the number of individual partiers who were at least 41 years old, we need to sum the frequencies of the age groups that start from 41 years old and above. Specifically, we will add the frequencies of the age groups 41-45 and 46-50.

Step 1: Identify Relevant Age Groups

To determine the number of partiers who are at least 41 years old, we focus on the age groups $41-45$ and $46-50$.

Step 2: Sum the Frequencies

We sum the frequencies of the identified age groups: \[ \text{Total} = \text{Frequency of } (41-45) + \text{Frequency of } (46-50) = 21 + 13 \]

Step 3: Calculate the Total

Calculating the total gives: \[ \text{Total} = 21 + 13 = 34 \]
