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 ??
