Question 1054214: CHECK MY ANSWERS PLEASE.......
Every year, the students at a school are given a musical aptitude test that rates them from 0 (no musical aptitude) to 5 (high musical aptitude). This year's results were:
Aptitude Score 0 1 2 3 4 5
Frequency 1 2 5 5 6 4
The average (mean) aptitude score: TOTAL STUDENTS : ADD UP FREQUENCIES 1+2+5+5+6+4=23
{0,2,5,5,5,5,5,6,6,6,6,4,4,4,4,4}
0(0)+2(1)+5(2)+5(3)+6(4)+4(5)=71
MEAN=71/23 = 3.086 I ROUND TO 3.09
