A study of the career paths of hotel general managers sent questionnaires to an simple random sample of 260 hotels belonging to major U.S. hotel chains. There were 155 responses. The average time these 155 general managers had spent with their current company was 11.85 years. (Take it as known that the standard deviation of time with the company for all general managers is 3.8 years.) Find the margin of error for an 80% confidence interval to estimate the mean time a general manager had spent with their current company. Round your answer to 2 decimal places.
