0. Assume that the zinc mass for the population of AAA batteries is normally distributed with standard deviation of 0.15. Suppose now that a researcher wants to calculate the sample size needed to reduce the width of the resulting 95% confidence interval for the true population mean zinc mass for AAA batteries. What sample size is necessary to ensure that the resulting 95% confidence interval has a margin of error of (at most) 0.01? (1) 380 (2) 385 (3) 580 (4) 860 (5) 865
