Suppose that instead of having a sample of 10 batteries you have 20 batteries. Construct a 95% confidence interval, and contrast this interval to the interval found in question 1. What happens to the width of the confidence interval if the sample size is 20 instead of 10? Use the Confidence Interval for One Mean calculator for these questions. Hint: To find the script for the Confidence Interval for One Mean calculator, access Help, Sample Data, Calculators. In the pop-up box, select Summary Statistics. Make sure you chose the correct test, before entering the values. (please put your answer in this formatting: 99.999 to 99.999. Do not round up.) You are developing a new lightweight lithium battery. The target weight is 22 g. You measure 10 batteries. The average weight is 22.2 g, and the standard deviation is 0.15 g. Use the Confidence Interval for One Mean calculator for this practice.
