Extracted text: A manager wishes to see if the time (in minutes) it takes for their workers to complete a certain task will increase when they are allowed to wear ear buds to listen to music at work. A random sample of 9 workers' times were collected before and after wearing ear buds. Assume the data is normally distributed. Perform a Matched-Pairs hypotheis T-test for the claim that the time to complete the task has increased at a significance level of a = 0.01. (If you wish to copy this data to a spreadsheet or StatCrunch, you may find it useful to first copy it to Notepad, in order to remove any formatting.) Round answers to 3 decimal places. For this problem, Ha = Hafter - H_Before, where the first data set represents "after" and the second data set represents "before". H, : Ha = 0 H, a > 0 This is the sample data: Before After 50.5 68.3 46 56.6 43.8 48.7 51.3 55.1 46.9 54.7 34 33.9 52.8 71.8 45.8 68.3 40.3 65.7 What is the mean difference for this sample?
