Answer:
the mean age is greater
Step-by-step explanation:
The mean age is ...
(1/2)14 + (1/3)15 + (1/6)13 = 14 1/6
The median age is 14. (half the students are 14 or younger)
The mean age is greater.
_____
1 -1/2 -1/3 = 6/6 -3/6 -2/6 = 1/6 . . . . . 1/6 of the students are 13.
Answer:
Step-by-step explanation:
Given that half of the students in a freshman class are 14 years old one third are 15 and the rest are 13
If no of students are n, then we have
n/2 have ages as 14, n/3 as 15 and remaining n/6 as 13.
Average would be total/n
= [tex]\frac{\frac{14n}{2}+\frac{15n}{3} +\frac{13n}{6} }{n} \\=7+5+\frac{13}{6} =14.67[/tex]
Median would be middle entry when arranged in ascending order hence = 14
Mean > median
