Answer 2

Answer:

Mean=27

Median=28.125

Mode=30.9

Step-by-step explanation:

as per the tabular column:

Mean = ∑fi xi/∑ fi

=1350/50

Mean=27

Median = l +[(n/2 -cf)/f ] x h

=30 +(25 -28)/16 c 10

=30 -30/16

=240-15/8

=225/8=28.125

Median =28.125

Mode=Z= l +[ (f1-fo)/(2f1-fo-f2)] x h

=30 x (16-15) (2x16-15-6) ]x 10

=30 + 1/(32-21) x 10

=30 +10/11

=330+10/11

=340/11

=30.9

Mode=30.9
