Unoccupied seats on flights cause airlines to lose revenue. Suppose a large airline wants to estimate its average number of unoccupied seats per flight over the past year. To accomplish this, the records of 225 flights are randomly selected, and the number of unoccupied seats is noted for each of the sampled flights. Descriptive statistics for the data are as follows: "x-bar" = 11.596 and "s" = 4.103.
How large a sample size is required to vary population mean within 0.30 seat of the sample mean with 95% confidence interval?
