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. Two hundred and twenty-five flight records are randomly selected and the number of unoccupied seats is noted, with a sample mean of 11.6 seats and a population standard deviation of 4.1 seats. How many flights should we select if we wish to estimate μ to within 5 seats and be 95 percent confident?

A. 44

B. 3

C. 2

D. 110

E. 6

Unoccupied seats on flights cause airlines to lose revenue. Suppose a large airline wants to determine of the mean number of unoccupied seats on all its flights is greater than 10. To accomplish this, the records of 60 flights are randomly selected and the number of unoccupied seats is noted for each of the sampled flights. The sample mean is 11.4 seats and the sample standard deviation is 3.4 seats. Test the claim that mean number of unoccupied seats on...

Unoccupied seats at the Cardinal’s football stadium causes the football team to lose revenue. The Cardinal’s owner wants to estimate the mean number of unoccupied seats per game over the past few years. To accomplish this, the records of 225 games are randomly selected and the number of unoccupied seats is noted for each of the sampled games. The sample mean is 11.6 seats and the sample standard deviation is 4.1 seats. x-=

A airline wishes to estimate the mean number of seats that are empty on flights that use 737-airplanes. There are 189 seats on a plane. To do so, the airline randomly picks n=35 flights. For each flight, the number of empty seats is counted. The data are given below. 38, 42, 44, 42, 40, 45, 37, 31, 33, 36, 35, 39, 37, 37, 43, 38, 41, 27, 33, 35, 37, 46, 32, 35, 35, 42, 37, 41, 29, 40, 44,...

There was an SRS of 100 flights on a large airline (airline 1) that showed that 64 of the flights were on time. An SRS of 100 flights of another large airline (airline 2) showed that 80 of the flights were on time. Let p1 and p2 be the proportion of all flights that are on time for these two airlines. What is a 95% confidence interval for the difference p1-p2? (-.222, -.098) (-.263, -.057) (-.218, -.102) (-.283, -.038) (.098,...
