Answer 1

To find the mean

=(12×9)+(13×6)+(14×4)+(15×7)+(16×4)/9+6+4+7+4

=411/30

=13.7

so the mean is 13.7

To find the median there are 30 values and it is even so we take 2 numbers from the middle 13 and 14

=13+14/2

=27/2

=13.5

The mode is set of data which occurs mostly so the mode of this data is 12
