A medical researcher wants to investigate the amount of time it
takes for patients' headache pain to be relieved after taking a new
prescription painkiller. She plans to use statistical methods to
estimate the mean of the population of relief times. She believes
that the population is normally distributed with a standard
deviation of 17 minutes. How large a sample should she take to
estimate the mean time to within 2 minutes with 94% confidence?
