Hi All, I was wondering if you could help me with a sample exam question that my lecturer has not provided a solution to, I've attached the pdf of the original Question:
The quality control procedure used on a particular project is ‘Acceptance by
Variables’. The variable used for comparison is an index sample mean. The
sample mean is assumed to be Gaussian distributed with mean µ and variance of
s
2
/n where n is the number of samples. The value of s
2
is known to be 60 and n is
5. Good production has a mean µa of 80 or higher. Poor production is represented
by a mean µt of 68 or less. If the standard mean value for comparison is L = 73,
find the producer’s risk and the consumers risk. Saving Changes...

Sorry but you really need to do your own course work. It isn't actually going to help you to provide you answers to questions your lecturer clearly expects you to find out for yourself, and it certainly won't help prepare you for the real exam - you won't be able to ask us then! Saving Changes...

This isn't an assignment or anything it's a past paper, it probably won't even come up on the exam.
I'm just looking for some guidance on how to approach the question as risk analysis wasn't my strong point Saving Changes...
