Hi, I need help with these questions and I'm not sure what to do.

Res
A manufacturer of pharmaccutical products analyzes cach batch of a product to verify the concentration of the active ingredient.
The chemical analysis is not perfectly precise. In fact, repcaled mcasurements follow a normal distribution with mean e oqual to
the truc concentration and standard deviation o = 0.0071 grams per liter. Three analyses of one balch give concentrations of
0.8302, O.8994, and 0.9295 grams per liter. To estimate the truc concentration, give a 95% conlidence interval for p.
STATE: What is the concentration of the active ingredient in this batch?
PLAN: We will estimale the truc concentration by giving a 95% conlidence interval for the mean e of the distribution.
SOLVE: Find the mean of the measurements. (Enter your answer rounded to four decimal places.)

CONCLUDE: We are 95% conlident that the mcan concentration of the active ingredicnt is between the valucs for the kower
bound and the upper bound.
