Unoccupied seats on flights cause the airlines to lose revenue. Suppose a large airline wants to estimate its average number of unoccupied seats per flight over the past year with the standard deviation of 4.1 seats. To accomplish this, the records of 225 flights are randomly selected and the number of occupied seats is noted with a mean of 11.6 seats. Estimate the expected population mean number of unoccupied seats per flight using 90% confidence interval. a - b
