Given that the population standard deviation is 5.6, determine the minimum sample size needed in order to estimate the population mean so that the margin or error is at most E = 0.5 at the 90% confidence level. O 19 265 340 106 207 D Question 12 1 points A manufacturer produces piston rings for an automobile engine. It is known that ring diameter is normally distributed with o = 0.1 millimeters. If we want to construct a 95% confidence interval for the average diameter of all such piston rings to within 0.01 millimeters, how large is the sample size needed
