Sagot :

Answer:

[tex]the \: mean \: = \frac{481}{30} [/tex]

[tex]the \: median \: = 15.5[/tex]

[tex]the \: mode \: = 10.5[/tex]

Step-by-step explanation:

The mean :

28.5 × 1 + 26.5 × 3 + 24.5 × 3 + 22.5 × 3 + 20.5 × 6 + 18.5 × 3 + 16.5 × 8 + 14.5 × 6 + 12.5 × 10 + 10.5 × 14

_______________________

1+3+3+3+6+6+8+6+10+14

[tex] = \frac{974}{60} [/tex]

[tex] = \frac{487}{30} [/tex]

The median :

60 ÷ 2 = 30 the median is in 30~31

(16.5 + 14.5) ÷ 2 = 15.5

The mode :

10-11 have 14

the mode is 10.5

hope it helps!
