MATH 131 8/1 Lab 6 The goal of this lab is to form confidence intervals for quantitative data (V3) and to determin an appropriate sample size for a selected error tolerance. (6 points) Part 1: Confidence Intervals for Quantitative Data, V3 Name of V3: A. Using the sample mean and standard deviation from Lab 3, form a 95% confidence interval for the mean of your population. B. Use the method discussed in class to write the interval in statement form. It is not sufficient to write an algebraic inequality. You must write a statement of the form: "I am 95% confident that the actual mean age of U.S. Senators is between 54.2 and 60.1." C. Repeat A and B for a 99% confidence interval. D. State clearly the difference between these two confidence intervals. (Explain which is wider and why.)
