here are my answers
Q4 Assumed Mean one
d(bar) = 3.9
mean = 450.4875
s.d= 1.08
ii) Mean = 450.4875+180
s.d = 1.08(as SD is not affected by Addition)

My S.D is Correct!
But i need to ask about the second part of it abt the mean
The Mean is 450.4875

The mean is the mass of "Canned Food"
The second part said that if the can weight is 180g then calculate the mean mass of the foood

So shudnt it be 450.4875-180= 270.4875
This is the mean for the food in the can

please help me


I have one more querry
In Paper 2 Qs.11

Umm, no it asked bout the 'total mass' so we're gonna add the mean to it :)
In q.11 the answer equalled to 60 point something. Pardon, I vaguely remember the exact value :(

How did u calculated it?
I got the same answer. We were supposed to find the value of the 85th percentile by linear interpolation formula.
