Confidence interval-true average number of seats per flights

Reference no: EM13125732

Unoccupied seats on flights cause airlines to lose revenue. Suppose a large airline wants to estimate the average number of unoccupied seats per flight. An SRS of 225 flights show a sample average of 11.6 seats per flight. Suppose standard deviation=4.1 and create a 90% confidence interval for the true average number of unoccupied seats per flight. interpret this interval in the context of the problem.
