This is the question:
< link to objectionable page removed >
This is what I'm doing:
I work out the middle number of each weight and add them up
175+
225+
275+
325+
375= 1375
then i add up the frequencies
3+4+5+6+2=20
Then I divide 1375 by 20 and get 68.75.
The answer at the back of my book is 272.5?
What am I doing wrong?
Homework is due tomorrow
