Hi, i've tried to solve this problem, but i have only ideas. Can you tell me if this is the way to solve this problem?. Thanks in advance!
Problem:
Resistance has a mean value of 330 ohms with a tolerance of 1% corresponding to 3 standard deviations. has an gaussian distribution. If
and
where, V is a 9 Volts constant voltage and has a value of 330 ohms.
- Calulate the mean and variance of
- Calculate the pdf of
My ideas:
Only and are random variables, and is a function of , thus . So, for the mean of :
right??
Or, should i calculate first the cdf with
or, directly the pdf with
Can you give me some tips and hints??
Thank you all!!
