(a) the mean number of musicians;

Answer 1

The mean number of musicians attending the seminars is 16. This is calculated by summing the number of musicians from each meeting and dividing by the number of meetings.

Step-by-step explanation:

The mean number of musicians attending a series of seminars on musicology is found by adding up the number of musicians at each meeting and then dividing by the total number of meetings. In this case, we add up the number of musicians from the 12 meetings: 22 + 16 + 20 + 20 + 15 + 16 + 12 + 14 + 16 + 14 + 11 + 16. This results in a total of 192 musicians. To find the mean, we divide this total by the number of meetings, which is 12. Therefore, the mean number of musicians per meeting is 192 ÷ 12, which equals 16.
