Question: Use the given information to find the minimum sample size required to estimate an un own population mean µ.
How many women must be randomly selected to estimate the mean weight of omen in one age group. We want 90% confidence that the sample mean is within 3.4 lb of the population mean, and the population standard deviation is known to be 25 lb.
