In addition to teachers and administrative staff, schools also have many other employees, including bus drivers, custodians, and cafeteria workers. The average hourly wage is $14.18 for bus drivers, $12.61 for custodians, and $10.33 for cafeteria workers. Suppose that a school district employs n = 36 bus drivers who earn an average of $11.45 per hour with a standard deviation of s = $2.84. Find a 95% confidence interval for the average hourly wage of bus drivers in school districts similar to this one. Does your confidence interval enclose the stated average of $14.18? What can you conclude about the hourly wages for bus drivers in this school district?
