MATH 131 Lab 6 (4 points) Part 2: Sample Size Determination 1/2021 A. Return Part 1A. What value did you calculate for E, the margin of error? 0.047.9 Choose a smaller value for E. 0.03 B. Calculate the minimum sample size required to produce a 95% confidence interval for the population mean with the smaller value for E. Show your calculations; use your sample standard deviation as an approximation for the population standard deviation. I will C. Write your answer in statement form like "With a sample size of at least be 95% confident that my sample mean will be within (smaller E value) year of the true mean (variable V3 name)" 2
