I need help with letter (b) so I got 11 numbers that are greater than the mean length, which I got( 648 divide by 20=32.4) ,so I set up a math proportion 100*11 and divide by 20 = 55% but in an answer book it said 45%, Am I doing something incorrect, if yes
Explain to me please.

11 out of 20 is 55%...are you sure you were asked for the percentage of the data greater than the mean?

Can you please state the numbers that are more than the average? I think if you do that then it will clear up everything for you. So please post back.

Okay, like you I get a mean of 32.4 mm, but I only count 9 data greater than the mean, specifically these values:

34, 39, 39, 41, 43, 43, 45, 51, 52
