Confidence Interval for Sample of Size n  1 Based on the article “An Effective Confidence Interval for the Mean with Samples of Size One and Two,” by Wall, Boen, and Tweedie (American Statistician, Vol. 55, No. 2), a 95% confidence interval for m can be found (using methods not discussed in this book) for a sample of size n = 1 randomly selected from a normally distributed population, and it can be expressed as x {9.68|x|. Use this result to construct a 95% confidence interval using only the first sample value listed in Exercise 21. How does it compare to the result found in Exercise 21 when all of the sample values are used?
