Your first assignment at El Smello Perfume Co. is to determine the proper setting for filling the bottles. The company wishes to keep profits high by using as little perfume as possible, but a government regulation states that no more than 2.5% of the bottles may contain less than the stated volume on the bottle. If the bottles you are filling are stated to contain 100 mL, what is the minimum volume you should use for filling if the uncertainty in the bottle wall thickness is ± 1.2 mL and the uncertainty in the fill level is ± 1.6 mL. (Hint: assume an infinite number of samples where the CI is X ± st and t= 1.96 for 95% confidence and 2.58 for 99% confidence).
heres my attempt.
CI=x-st for the lower bound since it asks for minimum V?
set CI = 100 and find X
s not sure if its just 1.2 + 1.6 or sqrt(1.2^2+1.6^2)
t not sure if i just use 95% or interpolate for 97.5
let me know what's the correct way? thanks
