Suppose you want to create a confidence interval for the number of almonds contained in a certain kind of candy bar. Assume the population is known to be approximately normal with a standard deviation of 2.15 almonds. What is the minimum sample size needed so that a 90% confidence interval has a margin of error equal to 0.25 almonds?
