To estimate the mean number of days that an employee was absent from work last year, Hamilton Manufacturing took a random sample of 600 of its employees. The mean of the sample was 16.3. It is known that the population standard deviation is σ=5.1. The 95% confidence interval was therefore approximately 16.3± m. What is the width of the confidence interval
