For the lots with defective components of more than 5 , the mean number of defective components per lot is 6.4 . Find the mean number of defective electronic components per lot for the given 500 lots.

this is what i did .

for the mean for ( 6 or more ) : x=16(6.4)=102.4

so overall mean = ( 1+2+3+4+5+102.4)/500 =0.24

Am i right ??
