I'm trying to determine the percentage of an area in a distribution that falls above a certain data point. However, this distribution is for a characteristic that has a one-sided tolerance limit (target is 0.00 with an upper limit of 0.09), and therefore is not a normal distribution. I did not know if using the Z-Tables is appropriate since it is not a normal distribution.
I was trying to find the percentage above 0.04. The average for the data is 0.026 and a standard deviation of 0.015 The way I calculated it was to treat it as a normal distribution and to find the theoretical percentage that falls below 0.00 by using the Z-Tables. I then subtracted 100% from this value to obtain the total area of the distribution. I then calculated the percentage below 0.04 and subtracted this value from the total to obtain the percentage above 0.04. Therefore, the percentage I calculated above 0.04 was 12.87%. Is this the correct method?

The format or location of your documentation has nothing to do with having to control it.
Any documentation (in any form or type of medium) needed by the organization to ensure the effective planning, operation and control of it's processes, must be controlled at least to the extent required in ISO 9001 section 4.2.3.
