11

Answer 1

Explanation:

since the data is already arranged in ascending to descending u don't have to change.

upper quartile (Q3) = 3(n + 1)/4 (n means no of data)

=3(10 + 1)/4

=3*11/4

=33/4

=8.25

=8 th term + 0.25(9 th term - 8 th term)

=11 + 0.25(13 - 11)

=11 + 0.25*2

=11 + 0.5

=11.5
