Answer:
<h3>Greater than 20</h3>
Step-by-step explanation:
Since mean is the average number of students, the formula for calculating the mean attendance of students is expressed as;
Mean = total number of student/sample size
Given mean = 20
Since the question talks about the first four meetings, the sample size = 4
<em>Since the sum total of students for the first four meetings is 80, hence the number of students who attended the meeting is greater than 20</em>
