Using techniques from an earlier section we can find a confidence interval for H Consider a random sample of n matched data pairs A B Let d B A be a random variable representing the difference between the values in a matched data pair Compute the sample mean d of the differences and the sample standard deviation s If d has a normal distribution or is mound shaped or if n 30 then a confidence interval for u is as follows d E d E where E t 5d Jn c confidence level 0 c 1 t critical value for confidence level c and d f n 1 B Percent increase for company A Percent increase for CEO USE SALT 20 12 24 18 6 4 21 37 22 22 24 14 4 19 15 30 a Using the data above find a 95 confidence interval for the mean difference between percentage increase in company revenue and percentage increase in CEO salary Enter your answer in the form lower limit to upper limit Include the word to Round your numerical values to two decimal places Your answer cannot be understood or graded More Information
