Repeat the above, except now find a 90% confidence interval to estimate the true mean word length for all of the words in the Gettysburg Address Use the Gettysburg Address applet (located on the course website in the Chapter 9 folder or here ) to take another random sample of 25 words. Set the sample size to 25 and number of samples to 1. Mean: and the sample standard deviation: Now, find the 90% confidence interval. Write the correct t multiplier here (Use the t-Distribution Critical Values table on p. A-7 in your text.) Margin of error: (Show work please!) Interval: (Show work please!) 7. Provide an interpretation of the results. Remember that you will need to report the interval estimate, and the level of confidence in your interpretation. 8. Did the interval you found include the true mean word length of 4.29? 9. What percentage of all the intervals in the class would you expect to NOT overlap the population mean? Explain
