What shape would youexpect this histogram to be? Why?
Where do you expectthe histogram to be centred?
How much variabilitywould you expect among these proportions?
Explain why a Normalmodel should not be used here.
The answer is
1, symmetric
2, 0.5
3, 0.125
4. np=8<10
Please explain why the third question has answer 0.125. how didyou get it?
