To find the mean, we need to first find the product of interval and frequency for each row, add all these products, and then divide by the total frequency sum.

The calculation would look like this:

((11*4) + (12*2) + (13*4) + (14*6) + (15*9)) / (4+2+4+6+9) = 40.83

Rounding to the nearest integer gives us a mean of 41.
